More about length and distance

General information

Length is the largest measurement of the body. In three dimensions, length is usually measured horizontally.

Distance is a measure of how far two bodies are from each other.

Distance and length measurement

Distance and length units

In the SI system, length is measured in meters. Derived quantities such as kilometer (1000 meters) and centimeter (1/100 meter) are also widely used in the metric system. In countries that do not use the metric system, such as the US and the UK, units such as inches, feet, and miles are used.

Distance in physics and biology

In biology and physics, lengths are often measured much less than one millimeter. For this, a special value, a micrometer, has been adopted. One micrometer is equal to 1×10⁻⁶ meters. In biology, micrometers measure the size of microorganisms and cells, and in physics, the length of infrared electromagnetic radiation. A micrometer is also called a micron and sometimes, especially in English literature, is denoted by the Greek letter µ. Other derivatives of the meter are also widely used: nanometers (1×10⁻⁹ meters), picometers (1×10⁻¹² meters), femtometers (1×10⁻¹⁵ meters), and attometers (1×10⁻¹⁸ meters).

Distance in navigation

Shipping uses nautical miles. One nautical mile is equal to 1852 meters. Initially, it was measured as an arc of one minute along the meridian, that is, 1/(60 × 180) of the meridian. This made latitude calculations easier, since 60 nautical miles equaled one degree of latitude. When distance is measured in nautical miles, speed is often measured in nautical knots. One knot is equal to one nautical mile per hour.

distance in astronomy

In astronomy, long distances are measured, so special quantities are adopted to facilitate calculations.

astronomical unit(au, au) is equal to 149,597,870,700 meters. The value of one astronomical unit is a constant, that is, a constant value. It is generally accepted that the Earth is located at a distance of one astronomical unit from the Sun.

Light year equals 10,000,000,000,000 or 10¹³ kilometers. This is the distance that light travels in a vacuum in one Julian year. This value is used in popular science literature more often than in physics and astronomy.

Parsec approximately equal to 30,856,775,814,671,900 meters or approximately 3.09 × 10¹³ kilometers. One parsec is the distance from the Sun to another astronomical object, such as a planet, star, moon, or asteroid, with an angle of one arc second. One arc second is 1/3600 of a degree, or about 4.8481368 mrad in radians. Parsec can be calculated using parallax - the effect of a visible change in the position of the body, depending on the point of observation. During measurements, a segment E1A2 (in the illustration) is laid from the Earth (point E1) to a star or other astronomical object (point A2). Six months later, when the Sun is on the other side of the Earth, a new segment E2A1 is drawn from the new position of the Earth (point E2) to the new position in space of the same astronomical object (point A1). In this case, the Sun will be at the intersection of these two segments, at point S. The length of each of the segments E1S and E2S is equal to one astronomical unit. If we postpone the segment through the point S, perpendicular to E1E2, it will pass through the intersection point of the segments E1A2 and E2A1, I. The distance from the Sun to point I is the SI segment, it is equal to one parsec when the angle between the segments A1I and A2I is two arcseconds.

On the image:

A1, A2: apparent star position
E1, E2: Earth position
S: position of the sun
I: point of intersection
IS = 1 parsec
∠P or ∠XIA2: parallax angle
∠P = 1 arc second

Other units

League- an obsolete unit of length used earlier in many countries. It is still used in some places, such as the Yucatan Peninsula and rural areas of Mexico. This is the distance a person walks in an hour. Marine League - three nautical miles, approximately 5.6 kilometers. Lie - a unit approximately equal to the league. In English, both leagues and leagues are called the same, league. In literature, the league is sometimes found in the title of books, such as "20,000 Leagues Under the Sea" - the famous novel by Jules Verne.

Elbow- an old value equal to the distance from the tip of the middle finger to the elbow. This value was widespread in the ancient world, in the Middle Ages, and until modern times.

Yard used in the British imperial system and is equal to three feet or 0.9144 meters. In some countries, such as Canada, where the metric system is adopted, yards are used to measure the fabric and length of swimming pools and sports fields and grounds, such as golf and football courses.

Meter Definition

The definition of the meter has changed several times. The meter was originally defined as 1/10,000,000 of the distance from the North Pole to the equator. Later, the meter was equal to the length of the platinum-iridium standard. Later, the meter was equated to the wavelength of the orange line of the electromagnetic spectrum of the krypton atom ⁸⁶Kr in vacuum, multiplied by 1,650,763.73. Today, a meter is defined as the distance traveled by light in a vacuum in 1/299,792,458 of a second.

Computing

In geometry, the distance between two points, A and B, with coordinates A(x₁, y₁) and B(x₂, y₂) is calculated by the formula:

Post a question to TCTerms and within a few minutes you will receive an answer.

Calculations for converting units in the converter " Length and distance converter' are performed using the functions of unitconversion.org .

Almost every person must have heard the expression "linear meter". For many, this definition remains quite complicated, since it is not at all clear what is the difference between sq. m. from the usual. What is the conversation about?

One linear meter equals the usual length of one meter. It is used to measure goods that have a certain width, for example, linoleum. It is much easier to calculate the cost of goods, taking running meters as a basis, than to calculate the cost of a square one.

For example, you need to buy carpet in the store, 2.5 wide and a certain length. Make a calculation of 1 m2, such a segment is not very convenient. To do this, you need to determine the area of \u200b\u200bthe product. Then divide it into squares. In other words, it is necessary to perform complex mathematical calculations.

It's much easier to do calculations on a per-square basis. To determine the cost of the goods, you will need to multiply the length of the segment of the carpet by the number of meters.

There is a fairly large list of goods in which the cost is calculated by the number of running meters. These include.

Fabrics.
Linoleum.
Carpet.
Finishing film.
Roll polyethylene.
Electric wires.
All kinds of pipes.
Various fences.
Fences.

Furniture calculation

A lot of consumers believe that the calculation by running meters applies only to rolled materials. However, this opinion is not entirely correct. When buying a product, we often come across a certain roll width. Linear very often determine the cost of furniture.

To make it clear, let's look at the following example.

The furniture manufacturer made an approximate calculation. To completely fill the three-meter kitchen, taking into account all the details of the furniture, he will need 30,000 rubles. Therefore, the cost of 1 m of furniture will be 10,000 rubles. In other words, such a cost will correspond to the price of one running meter. Based on such fairly simple mathematical calculations, the furniture manufacturer can tell the customer what the cost of a set of furniture of the corresponding sample will be.

However, one important nuance must be taken into account. When calculating the price m, only the cost of the cheapest fittings and material was taken into account. Sometimes the cost of fittings is not included in the calculation at all.

Therefore, if a very tempting offer is made to you, you must definitely find out what material the product is made of, what accessories are installed on it. In this way, quite often attract new customers.

How many mm in a linear meter

As already mentioned, one linear meter is equal to one standard meter. From this it turns out that there are 1000 mm in 1 linear meter.

cheat sheet

So, to make it easier to deal with units of measurement, they can be summarized in one table, in which their ratio will be visible, and it will be quite easy to convert one unit to another.

What does the term "square meter" mean?

This unit is designed to calculate the area of a square, in which each of the sides will be 1 meter. To determine the size of the area, you need to multiply the height and length of the product. For designation, the short form is used - sq. m.

Today, this unit is found in our lives almost everywhere. The most obvious example is the dimensions of a dwelling. In other words, if we are talking about an apartment of 16 m2, then the floor area is equal to this value.

The square meter is most commonly found in the construction industry. To determine the area of a wall that is 6 meters long and 4 meters high, simply multiply six by four. It turns out that the area of \u200b\u200bthe wall is 24 m2.

Everything is measurable. It is a fact. But the values used are different. Most of the products that are rolled up, which relate to fittings and kitchen products, are today measured in running meters. To be more precise, a running meter is how many meters in length. The width is not taken into account.

In one store, these stripes are in this form. But in the other there is just one wide strip of 3 meters long 10 meters. In essence, this is what we need. Since the cost is indicated in running meters, in the first store we will pay three times more than in the second. The savings are huge!

Remember, 1 linear meter is 1 meter of the product in length. And then it doesn't matter what the width is. The price will not change.

Carefully!

Very often, only the number of linear meters and the price are indicated in the product information card. This means that we do not know anything about the width of the product. If you buy everything in a store or market, you can bring your own tape measure.

On the Internet, such data is often hidden. You can not order a product without making sure of its parameters. It is worth calling the store and find out its width.

When you find two identical items with different prices, do not rush to order the cheapest one. It is possible that the width of that product will not suit you.

Marking the fabric is a matter, although not simple, but accurate. With kitchens, which are also measured in linear meters, everything is much more complicated. Usually, we take into account 1 meter of standard headset. That is, simple cabinets and tables are always used for miscalculations. All additional decorative elements are negotiated separately.

If you buy a ready-made kitchen, then information about running meters is not particularly important. You already see the finished price tag and decide whether the price is right or not. But with individual orders, you need to carefully consider everything.

It is important to emphasize that you can never know the exact amount in advance. We can only judge the minimum cost of 1 linear meter of your future kitchen.

There are two popular situations in which the answers are completely different:

1. Accurate calculation. You order an ordinary kitchen, where all drawers, cabinets and tables are of standard sizes. You don't change anything. The final price may differ slightly from the planned one.

2. Completely inaccurate calculation. The kitchen is completely original. All cabinets and drawers are designed for your convenience and size of dishes and furniture. The headset fits exactly into the design of the room. The final price may be several times higher.

Why is the total going up?

It is difficult to translate linear meters. And for the sake of a new idea, you have to put up with the pricing policy. To cut costs, it is worth connecting different components. That is, it is necessary to use as many standard elements as possible, diluting them with custom ones. So you get a kitchen that fits well into the interior, and save your budget.

Do not forget that different materials and design features increase the cost. One linear meter of a locker can become more expensive if you decide to install not 4, but 5 drawers in it. Each detail requires additional expenses. Carving or decorative stickers are far from cheap.

Alternative to running meter

Many shops calculate the price based on ready-made kitchens. You choose the model you like, see its price, and then change it a little, if necessary. In such cases, it is easier to evaluate a future purchase.

As a result, we see that a linear meter is a value by which many goods are measured, from fabric to kitchen. It defines the length without specifying the width. In order not to make a mistake in the purchase, you need to clarify all the points. If the Internet refuses to tell you the width, then it's not worth the risk. After all, you can just lose your money.

The sun is the source of life on the planet. Its rays give the necessary light and warmth. At the same time, ultraviolet radiation from the Sun is detrimental to all living things. To find a compromise between the beneficial and harmful properties of the Sun, meteorologists calculate the ultraviolet radiation index, which characterizes the degree of its danger.

What UV radiation from the sun is

The ultraviolet radiation of the Sun has a wide range and is divided into three regions, two of which reach the Earth.

UV-A. Longwave radiation range
315–400 nm

The rays pass almost freely through all atmospheric "barriers" and reach the Earth.
UVB. Medium wave radiation range
280–315 nm

The rays are 90% absorbed by the ozone layer, carbon dioxide and water vapor.
UVC. Shortwave radiation range
100–280 nm

The most dangerous area. They are completely absorbed by stratospheric ozone without reaching the Earth.

The more ozone, clouds and aerosols in the atmosphere, the less the harmful effect of the Sun. However, these saving factors have a high natural variability. The annual maximum of stratospheric ozone occurs in spring, and the minimum - in autumn. Cloud cover is one of the most variable weather characteristics. The content of carbon dioxide also changes all the time.

At what values of the UV index is there a danger

The UV index gives an estimate of the amount of UV radiation from the Sun on the Earth's surface. UV index values range from safe 0 to extreme 11+.

0–2 Low
3–5 Moderate
6–7 High
8–10 Very high
11+ Extreme

In mid-latitudes, the UV index approaches unsafe values (6–7) only at the maximum height of the Sun above the horizon (occurs in late June - early July). At the equator, during the year, the UV index reaches 9...11+ points.

What is the benefit of the sun

In small doses, UV radiation from the Sun is essential. The sun's rays synthesize melanin, serotonin, vitamin D, necessary for our health, and prevent rickets.

Melanin creates a kind of protective barrier for skin cells from the harmful effects of the sun. Because of it, our skin darkens and becomes more elastic.

Happiness hormone serotonin affects our well-being: it improves mood and increases overall vitality.

Vitamin D strengthens the immune system, stabilizes blood pressure and performs anti-rickets functions.

Why is the sun dangerous?

When sunbathing, it is important to understand that the line between beneficial and harmful Sun is very thin. Excessive sunburn always borders on a burn. UV radiation damages DNA in skin cells.

The body's defense system cannot cope with such an aggressive impact. This lowers the immune system, damages the retina, causes skin aging and can lead to cancer.

Ultraviolet destroys the DNA strand

How does the sun affect people?

Susceptibility to UV radiation depends on skin type. The most sensitive to the Sun are people of the European race - for them, protection is required already at an index of 3, and 6 is considered dangerous.

At the same time, for Indonesians and African Americans, this threshold is 6 and 8, respectively.

Who is affected the most by the Sun?

people with light
skin tone

People with many moles

Residents of the middle latitudes while relaxing in the south

winter lovers
fishing

Skiers and climbers

People with a family history of skin cancer

In what weather is the sun most dangerous

The fact that the Sun is dangerous only in hot and clear weather is a common misconception. You can also get burned in cool cloudy weather.

Cloudiness, no matter how dense it may be, does not at all reduce the amount of ultraviolet to zero. In mid-latitudes, cloud cover significantly reduces the risk of sunburn, which cannot be said about traditional beach holiday destinations. For example, in the tropics, if in sunny weather you can get burned in 30 minutes, then in cloudy weather - in a couple of hours.

How to protect yourself from the sun

To protect yourself from harmful rays, follow these simple rules:

Get less exposure to the Sun during the midday hours

Wear light-colored clothing, including wide-brimmed hats

Use protective creams

Wear sunglasses

Stay in the shade more on the beach

Which sunscreen to choose

Sunscreen varies in terms of sun protection and is labeled from 2 to 50+. The numbers indicate the proportion of solar radiation that overcomes the protection of the cream and reaches the skin.

For example, when applying a cream labeled 15, only 1/15 (or 7%) of the UV rays will penetrate the protective film. In the case of cream 50, only 1/50, or 2%, affects the skin.

Sunscreen creates a reflective layer on the body. However, it is important to understand that no cream is capable of reflecting 100% of ultraviolet radiation.

For everyday use, when the time spent under the Sun does not exceed half an hour, a cream with protection 15 is quite suitable. For tanning on the beach, it is better to take 30 and above. However, for fair-skinned people, it is recommended to use a cream labeled 50+.

How to apply sunscreen

The cream should be applied evenly to all exposed skin, including the face, ears and neck. If you plan to sunbathe for a long time, then the cream should be applied twice: 30 minutes before going out and, additionally, before going to the beach.

Please refer to the cream instructions for how much to apply.

How to apply sunscreen while swimming

Sunscreen should be applied every time after bathing. Water washes away the protective film and, reflecting the sun's rays, increases the dose of ultraviolet radiation received. Thus, when bathing, the risk of burning increases. However, due to the cooling effect, you may not feel the burn.

Excessive sweating and rubbing with a towel is also a reason to re-protect the skin.

It should be remembered that on the beach, even under an umbrella, the shade does not provide full protection. Sand, water, and even grass reflect up to 20% of UV rays, increasing their impact on the skin.
