More about the area

General information

Area is the size of a geometric figure in two-dimensional space. It is used in mathematics, medicine, engineering, and other sciences, such as calculating the cross section of cells, atoms, or pipes such as blood vessels or water pipes. In geography, area is used to compare the sizes of cities, lakes, countries, and other geographic features. Area is also used in population density calculations. Population density is defined as the number of people per unit area.

Units

Square meters

Area is measured in SI units in square meters. One square meter is the area of a square with a side of one meter.

unit square

A unit square is a square with sides of one unit. The area of a unit square is also equal to unity. In a rectangular coordinate system, this square is at coordinates (0,0), (0,1), (1,0) and (1,1). On the complex plane, the coordinates are 0, 1, i and i+1, where i is an imaginary number.

Ar

Ar or sotka, as a measure of area, is used in the CIS countries, Indonesia and some other European countries, to measure small urban objects such as parks, when a hectare is too large. One are is equal to 100 square meters. In some countries, this unit is called differently.

Hectare

Real estate is measured in hectares, especially land plots. One hectare is equal to 10,000 square meters. It has been in use since the French Revolution, and is used in the European Union and some other regions. As well as ar, in some countries the hectare is called differently.

Acre

In North America and Burma, area is measured in acres. Hectares are not used there. One acre is equal to 4046.86 square meters. Initially, an acre was defined as the area that a peasant with a team of two oxen could plow in one day.

barn

Barns are used in nuclear physics to measure the cross section of atoms. One barn equals 10⁻²⁸ square meters. Barn is not a unit in the SI system, but is accepted for use in this system. One barn is approximately equal to the cross-sectional area of the uranium nucleus, which physicists jokingly called "huge as a barn." Barn in English "barn" (pronounced barn) and from a joke of physicists, this word became the name of a unit of area. This unit originated during World War II, and scientists liked it because its name could be used as a code in correspondence and telephone conversations within the Manhattan Project.

Area calculation

The area of the simplest geometric figures is found by comparing them with the square of a known area. This is convenient because the area of a square is easy to calculate. Some formulas for calculating the area of geometric shapes below are obtained in this way. Also, to calculate the area, especially a polygon, the figure is divided into triangles, the area of \u200b\u200beach triangle is calculated using the formula, and then added. The area of more complex figures is calculated using mathematical analysis.

Area formulas

Square: square side.
Rectangle: product of the parties.
Triangle (side and height are known): the product of a side and the height (the distance from that side to the edge) divided in half. Formula: A = ½ah, where A- square, a- side, and h- height.
Triangle (two sides and the angle between them are known): the product of the sides and the sine of the angle between them, divided in half. Formula: A = ½ab sin(α), where A- square, a and b are the sides, and α is the angle between them.
Equilateral triangle: side, squared, divided by 4 times the square root of three.
Parallelogram: the product of a side and the height measured from that side to the opposite side.
Trapeze: the sum of two parallel sides multiplied by the height, divided by two. Height is measured between these two sides.
A circle: the product of the square of the radius and π.
Ellipse: product of semiaxes and π.

Surface area calculation

You can find the surface area of simple three-dimensional figures, such as prisms, by unfolding this figure on a plane. It is impossible to obtain a ball scan in this way. The surface area of a sphere is found using the formula by multiplying the square of the radius by 4π. From this formula it follows that the area of a circle is four times less than the surface area of a ball with the same radius.

Surface areas of some astronomical objects: Sun - 6.088 x 10¹² square kilometers; Earth - 5.1 x 10⁸; thus, the surface area of the Earth is about 12 times smaller than the surface area of the Sun. The surface area of the Moon is approximately 3.793 x 10⁷ square kilometers, which is about 13 times smaller than the surface area of the Earth.

planimeter

The area can also be calculated using a special device - a planimeter. There are several types of this device, for example, polar and linear. Also, planimeters are analog and digital. In addition to other features, digital planimeters can be scaled to make it easier to measure features on a map. The planimeter measures the distance traveled along the perimeter of the measured object, as well as the direction. The distance traveled by the planimeter parallel to its axis is not measured. These devices are used in medicine, biology, engineering, and agriculture.

Area properties theorem

According to the isoperimetric theorem, of all figures with the same perimeter, the circle has the largest area. If, on the contrary, we compare figures with the same area, then the circle has the smallest perimeter. The perimeter is the sum of the lengths of the sides of a geometric figure, or a line that marks the boundaries of this figure.

Geographic features with the largest area

Country: Russia, 17,098,242 square kilometers, including land and water. The second and third largest countries are Canada and China.

City: New York is the city with the largest area at 8,683 square kilometers. The second largest city is Tokyo, covering 6,993 square kilometers. The third is Chicago, with an area of 5498 square kilometers.

City Square: The largest area, covering 1 square kilometer, is located in the capital of Indonesia, Jakarta. This is Medan Merdeka Square. The second largest area at 0.57 square kilometers is Praça dos Giraçois in the city of Palmas, in Brazil. The third largest is Tiananmen Square in China, 0.44 square kilometers.

Lake: Geographers debate whether the Caspian Sea is a lake, but if it is, then it is the largest lake in the world with an area of 371,000 square kilometers. The second largest lake is Lake Superior in North America. It is one of the lakes of the Great Lakes system; its area is 82,414 square kilometers. The third largest is Lake Victoria in Africa. It covers an area of 69,485 square kilometers.

About, how many acres in one hectare and how to calculate all this correctly, you will learn by reading the following material in the article. Collected quality information.

I think any person at least once in his life will have or hectares. Then it will be useful for you to find out how many acres are in one hectare and how to calculate everything correctly.

The ability to convert hundreds into hectares or vice versa will be useful in various fields of activity: in construction, agricultural work, buying and selling land.

How is one hectare calculated

The most common unit of measurement for the area of agricultural land is the hectare. Visually, it can be represented as a square of 100 by 100 meters.

This unit of measurement usually shows the areas of large farms, parks, nature reserves, etc.

The area of a hectare can be determined using simple mathematical operations.

S \u003d 100 * 100 \u003d 10,000 m 2

That is, one hectare 10 thousand square meters.

It should not be confused with the square kilometer, which is also used to measure fairly large areas. One square kilometer is also a square, but with sides of 1000 meters.

It is generally accepted that if the land has sides whose length is within from 100 to 1000 m, then the hectare is taken as the unit of measurement.

How to measure the area of an irregularly shaped plot

It is not always necessary for us to measure and translate the area of the land plot of the correct form, what to do if we have to work with trapezoidal or round territories.

If the land plot has a round shape, then apply the formula for calculating the area of a circle, this is S \u003d n r 2, where n is the number Pi (3.14), and r is the radius.

In the event that the site is uneven, or it is too difficult to visually divide it into simpler shapes, then you should contact specialists who, using the necessary equipment and instruments, will provide you with accurate information about the area and then it will be possible to convert it into the desired units.

It is worth considering that experts calculate the area in square meters and round it up to 1 m 2.

First, you need to explain what a cell is. One acre is a plot, the size one hundred one hundred. That is, its area is 100 m 2. Weaves are used if you need to measure a relatively small area, for example, for a summer cottage or a garden.

By the ratio of the areas of one hectare and one weave, you can find out the answer to the question posed at the beginning of the article.

10,000 m 2 / 100 m 2 \u003d 100

That is, in one hectare can be "put in" 100 acres.

How to convert hundreds to hectares

It is quite easy to do this. This is where some basic math comes in handy. In order to convert acres to hectares, you need to add the proportion. For example, you need to convert 27 acres to hectares (hectares).

We already know that in one hectare there are 100 acres, and, for example, in X(x) hectares - 27 acres. Then the proportion looks like this:

Respectively, X= 1*27/100. Eventually, X equals 0.27 hectares. This will be the area of the plot, presented in hectares.

If you are afraid of making a mistake, then you can use special online convectors that will convert acres to hectares in a few seconds, or vice versa.

In order to better remember how many acres are in one hectare, the following figure is for you:

In order to find out how many hectares are in a square meter, you need to use a simple online calculator. Enter in the left field the number of square meters you are interested in, which you want to convert. In the field on the right you will see the result of the calculation. If you need to convert square meters or hectares to other units, just click on the appropriate link.

Square meter (m², m²) is a unit of area measurement adopted in the SI, MTS and MKGSS systems. One square meter is equal to the area of a square with a side of 1 m. There are 10,000 square centimeters in one square meter.

What is "hectare"

Hectare (ha, ha) is an off-system unit of area measurement. One hectare is equal to the area of a square with sides of 100 m. This unit was adopted by the International Committee for Weights and Measures in 1879, and is currently used together with SI units. On the territory of the Russian Federation in hectares measure the area in forestry and agriculture. Along with hectares, measurements are carried out in hundredths, equal to one hundredth of a ha (100 sq. M).

The concept of "hectare" was put into practice after 1917 and replaced the tithe - 1 ha was equal to 11-12 tithes. Since the 1930s, the abbreviated version "ha" has entered everyday speech. To visualize an area of one hectare, imagine a rugby field (1.008 hectares) or a football field (0.714 hectares).

1 acre = 4840 square yards = 4046.86 m 2

The most commonly used land measure in practice is hectare - the abbreviation ha:

1 ha = 100 are = 10,000 m 2

In Russia, a hectare is the main unit for measuring land area, especially agricultural land.

On the territory of Russia, the unit "hectare" was put into practice after the October Revolution, instead of the tithe.

Old Russian units of area measurement

1 sq. verst = 250,000 sq. fathoms = 1.1381 km²
1 tithe = 2400 sq. fathoms = 10,925.4 m² = 1.0925 ha

The area of land plots for individual housing construction, private household plots is usually indicated in acres

One hundred- this is the area of \u200b\u200ba plot measuring 10 x 10 meters, which is 100 square meters, and therefore is called a hundred.

Here are some typical examples of the sizes that a land plot of 15 acres can have:

In the future, if you suddenly forget how to find the area of a rectangular plot of land, then remember a very old joke when a grandfather asks a fifth grader how to find Lenin Square, and he answers: “You need to multiply the width of Lenin by the length of Lenin")))

It is useful to know this

For those who are interested in the possibility of increasing the area of land plots for individual housing construction, private household plots, gardening, horticulture, which are owned, it is useful to familiarize yourself with the procedure for registration of cuts.

From January 1, 2018, the exact boundaries of the site must be recorded in the cadastral passport, since it will simply be impossible to buy, sell, mortgage or donate land without an accurate description of the boundaries. This is regulated by amendments to the Land Code. A total revision of the borders at the initiative of the municipalities began on June 1, 2015.

On March 1, 2015, the new Federal Law “On Amendments to the Land Code of the Russian Federation and Certain Legislative Acts of the Russian Federation” (N 171-FZ “dated June 23, 2014) came into force, in accordance with which, in particular, the procedure for buying land plots from municipalities was simplifiedYou can read the main provisions of the law here.

With regard to the registration of houses, baths, garages and other buildings on land owned by citizens, the situation will improve with a new dacha amnesty.

How many square meters in a hectare?

How many acres in 1 hectare

Excavation

Despite the fact that we often see the concepts of “hundred”, “hectare”, “square meter” in various sources, many people have difficulties when it comes to converting one of the measures of area measurement to another. In fact, there is nothing complicated in this process.

Units of land area measurement

All three concepts denote a measure of area.

It is very easy to remember how many acres are in 1 hectare and how many square meters. The title itself already contains a clue.

Just remember the ratios:

1 ha = 100 acres,

1 weave = 100 square meters (m2),

1 ha = 10,000 square meters.

As you can see, everything is very simple, it is enough to know this simple formula and be able to apply it.

For example, there is a plot of 20 hectares. In order to find out how many acres are in it, we multiply 20 (the total number of hectares) by 100. We get the following equation:

That is, twenty hectares contain 20 acres.

In the same way, weaving can be converted to hectares. Let's say we know that this area has 300 acres, and we need to measure it in hectares. Again, we recall how many acres are in 1 hectare, and we get:

That is, our plot of three hundred acres contains only three hectares.

Similarly, you should act if you need to convert square meters to hundredths or hectares and vice versa.

Let's take our plot of 20 hectares. We know that one hectare contains 10 thousand square meters. Therefore, the conversion to square meters will look like this:

20x10000 = 200000, that is, in 20 thousand hectares - two hundred thousand square meters.

Now let's calculate how many square meters are in 10 acres. As we remember, 1 weave is one hundred square meters, therefore, we get the following calculation:

10x100=1000 sq.m.

Despite the fact that all of these quantities are a measure of the area, they are used in different cases.

In square meters, the area of \u200b\u200bhousing is most often measured, as well as small plots, the size of which is less than 10 meters in length and 10 in width.

In this way, small building plots or country plots can be measured. The size of the land area, which is usually measured in acres, does not exceed 100 meters in length and a hundred in width. Larger plots (one measurement over 100 meters) are already measured in hectares. And if one of the dimensions of the site is more than a thousand meters, then it can be measured already in square kilometers. So it's not so difficult to calculate it all on your own, knowing a simple formula.

Quick answer: There are 10,000 square meters in one hectare.

A hectare (ha) is a metric unit of area (this is the common name for the international decimal system of units, which is based on the use of kilogram and meter), equal to the area of a square with a side of 100 meters. In total we have: 1 ha = 10,000 m2 = 100 ar = 100 acres.

How much per hectare

In our country, a hectare is considered the main unit of land area measurement, in particular, agricultural. We also often use another unit of area - weaving, which is equivalent to one hundredth of a hectare. Interestingly, until 1917, another value was used on the territory of our country, called a tithe: it is believed that it arose before the 15th century and was equal to 2400 square sazhens. It was a rectangle with sides of 60 by 40 fathoms or 80 by 30. As for the hectare, this unit began to be used immediately after the October Revolution and the ratio 1 ha = 11/12 tithes was used for translation. The abbreviation "ha" began to be used around the 30s.

By the way, why do we need this unit? Let's say you want to buy a plot for the construction of a summer house or a capital house. The ads usually indicate hundreds, but often hectares. It is clear that 1 hectare is a huge amount of land on which you can safely build several tens or even hundreds of houses. True, the cost of 1 hectare of land is certainly an absolutely exorbitant amount. In addition, hectares are usually sold not for development, but for planting crops.

How many acres in one hectare- this question may be of interest to people who are going to buy or rent a large area of land. Having personal possessions, for example, a country house, we most often encounter such a measure of land area as a weave. An ordinary summer resident does not need hectares of land. It is enough to build a house, equip a flower bed, a barbecue, and even a pool - that's all the needs of a summer resident. But when planning, for example, to engage in agriculture, it will not be possible to limit one hundred square meters, hectares of land are of interest. And this is where the inevitable question arises: 1 hectare - how many acres makes up. To be honest, one hectare is clearly not enough to run a serious agricultural business. And people with experience are well versed in the basics of the school curriculum, especially when it comes to land resources.

A hectare is a metric unit of area. To imagine a hectare, it is enough to imagine a square with a side of 100 meters. Knowing from the course of school mathematics how the area of a square is measured, it is already easy to determine the area of \u200b\u200ba hectare.

1 ha = 100 x100

One hectare corresponds to 10,000 square meters. To understand how many acres in 1 hectare, you now need to remember what a weave is, how the area of \u200b\u200bone weave is calculated and calculate how many acres can fit in one hectare.

One weave is a square, each side of which is equal to 10 meters. The area of 1 acre is:

1 weave = 10 x 10

One acre equals 100 square meters. To calculate how many acres in 1 ha, it is necessary to compare the areas occupied by a hundred and a hectare.

1 weave = 100 sq.m.

1 hectare = 10,000 sq.m.

10,000 sq.m. / 100 sq. m = 100

From the calculation it is obvious how many acres are in a hectare. There are 100 acres in a hectare, and a hundredth is a hundredth of a hectare. A plot of 100 square meters is the weave of land. Here are 100 such plots and you already have a hectare of land.

Acres are used to determine the area of dacha garden plots, as well as plots for construction. To determine the area of large sizes, such as cities, for example, use the unit of area - 1 square kilometer. If you notice, then in the reference literature with the characteristics of states, cities, the area is indicated in square kilometers. But for plots of land with a side of more than 100 meters, but less than 1 kilometer, it is more convenient to use the unit of measurement - 1 ha.

It is difficult for people who are accustomed to calculate the area in square meters to visualize how many acres are in hectares, and it is just as difficult to convert acres to hectares and vice versa.

A square kilometer is a square with each side of 1000 meters (1 km), and a hectare is a square with a side of 100 meters.

The area of 1 square kilometer is 1 million square meters.

1 sq. km = 1000 x 1000

Area of 1 hectare - 10,000 sq. meters (1 ha = 100 x 100)

Therefore, 1 square kilometer is 100 times larger than 1 hectare. Similarly, we determine: 1 ha - how many acres are in the composition. One weave covers an area of 100 square meters. Therefore, in comparison with a hectare, weaving is 100 times less than a hectare.

In the international system of measures, a hectare (according to the dictionary, the name from the Greek word hecto - one hundred, abbreviated hect.) is the most used, because. its “trick” is that with its help it is most convenient to measure areas whose area is more than ten thousand square meters (not centimeters or dm2 to use in this case), plus make a mistake in translating 1 hectare into any other unit of measurement that can be called , (even off-system, for example, yard, acre), is almost impossible.

However, if, for example, the use of this unit still continues to be difficult for you, then you can easily find an online free calculator converter on the advice of the forum, and use it for all your calculations. So you can reduce the time that will be used for calculations. In general, in order to help the client understand how much land he needs and find the exact dimensions, we use this particular calculator, as well as a visualization program that links real and reduced scales.

In an instant, it can form exactly the same pattern as in life, but smaller. In this case, looking at an approximate "photo" of their future site, customers always understand what they need. I would advise all construction companies to take a closer look at such software.

Hello, dear readers of the blog site. In this article, we will explain in detail what HECTAR is.

Many people know that this is the name of the measure for calculating the area of \u200b\u200bany territory. And they know that this is a fairly large value.

But even these people in most cases find it difficult to name the exact definition and size of a hectare.

How much is a hectare?

A hectare is a non-systemic unit of area measurement. Outwardly, it looks like square, with each side having a length of 100 meters. And the area of such a geometric figure is a hectare.

To make it clearer, just take a look at the following figure.

The square marked with red lines has a side length of 100 meters. And if you remember simple mathematical rules from the school curriculum - to calculate the area of a rectangle (and a square in particular), you need to multiply the lengths of the two sides. In our case:

Which means 10 thousand square meters and can be considered a hectare.

The number is really impressive. Therefore, the term itself is used, as a rule, in agriculture and forestry. But for summer cottages, it is not very suitable, since there we are talking more often about smaller areas.

And to make it even easier to visually understand what a hectare is, let's give a few examples:

Football field - 0.714 hectares
Red Square in Moscow - 2.31 hectares
The area of the whole of Moscow is 256,100 hectares

By the way, many mistakenly confuse hectares and square kilometers, believing that they are one and the same.

But this is a gross mistake! After all square kilometer is a square with a side of 1000 meters. A "square hectare" is 10 times smaller in length and width.

That is, you can draw some kind of regularity.

One square kilometer contains 100 hectares. And in one hectare - 100 acres (ar). So, one square kilometer is 10,000 acres.

Origin of the word "hectare"

The term HECTAR has two roots at once. One of the "hects" comes from the ancient Greek "ἑκατόν", which means " hundred". And the second root is ar».

AR- this is another, so-called, off-system unit for calculating the area, which also represents square, but with side length 10 meters. So its area is:

From here, by the way, comes the more familiar to us and more popular name "ara" - SOTKA.

That is, it turns out that the term HECTAR means "one hundred acres". And this is exactly the same 10 thousand square meters that we have already talked about.

Why is a hectare called "off-system"

If you carefully read the definitions of HECTARE, you could pay attention to the phrase "non-systemic unit of area". By the way, ARA has the same thing. Let's explain what this means.

First of all, it must be said that the use of the term HECTARE began in 1879. Official permission was issued by the International Committee for Weights and Measures.

This is an organization that ensures that the same instruments and quantities are used all over the world when measuring length, weight, time, and so on. Otherwise, there would be a terrible mess.

Just imagine that in France there would be meters and kilometers, and in Russia they would continue to measure the distance in arshins and cubits in the old fashioned way.

So this same International Committee of Weights and Measures in 1879 allowed the use of HECTAR in measuring the area. At the same time, abbreviated designations for this quantity appeared - “ha” and “ha”.

But the permission of the International Committee of Weights and Measures came into conflict with the older and more authoritative SI system of units. It was founded a hundred years earlier (1770) and is a collection of standards for units of measurement of various parameters.

What these parameters are can be seen from the following table.

So in the system SI no hectare simply could not exist, since the length (and, accordingly, the area) is responsible METR and its derivatives- millimeter, centimeter, decimeter, kilometer and so on.

But the SI system allows the use of "foreign" units of measurement. They are called " off-system". By the way, a hectare in this list is in a very representative company. The same category includes, for example, minute, hour, day, ton, centner and liter.

How to convert hundreds and square meters to hectares

As we have already said (more than once), one hectare contains 100 acres and 10 thousand square meters.

Accordingly, in order to convert one measure of area into another, it is necessary to carry out very simple calculations.

So, to convert acres to hectares, you need to multiply them by 0.01. And to convert square meters to hectares, you need to multiply by 0.0001.

Example. It is necessary to determine which is more - 20 acres or 500 square meters.

To solve this problem, let's convert both values to hectares. Accordingly, 20 acres is:

20 * 0.01 = 0.2 hectares.

And 500 square meters is:

500 * 0.0001 = 0.05 hectares.

And it turns out that in our example, 20 acres is more than 500 square meters.

It is just as easy to do the reverse calculations. For example, when the value of the area in hectares is known, but it is required to convert it into square meters or acres.

There are quite simple circuit, which helps to quickly convert hectares to acres and other area measurements. Its essence is explained in this video.

That's all we wanted to talk about such a term as HECTARE. See you soon on our blog pages.
