  • An ounce-force is a measure of weight, that is, mass.
  • A fluid ounce is a measure of volume.

Historically, it was used in many industries in various fields where it was required to measure mass or volume.

Name etymology

Where did the term "ounce" come from? This name comes from the Latin uncia - a unit that was one twelfth of the Roman pound (measure of weight).

The name was borrowed twice. At first, Old English was spoken "insan" or "indsan" (this is a corrupted form of Latin). Then, in late medieval English, the word "ounce" began to be used.

The abbreviation oz came later from the related Italian word onza (now spelled oncia).

Why there is no single standard

An ounce is a unit that is measured in many different ways. The explanation for this is as follows. It has been used historically in many parts of the world, at different points in history and for various applications. Therefore, unequal mass standards were taken as a basis.

How much does an ounce weigh in different values? The international version of avoirdupois calls 28.349523125 437.5 grams. An international troy ounce is 31.1034768480 grams, a French ounce is 30.59 grams. There are other numbers as well. It is worth learning more about what types of this unit of measurement are used in the modern world.

International avoirdupois system (oz)

An international ounce is 28.349523125 grams, according to the International Yard and Pound Convention of 1959. It was signed by the United States of America and the countries of the Commonwealth of Nations.

In the Avoirdupois system, sixteen ounces make up a pound with the same name. It is defined as follows: 7000 grains. Therefore, one ounce totals 437.5 grains.

It is still the standard unit of weight in the United States. In the UK, it ceased to be a legal unit of measure in 2000, but is still widely used on an informal basis. In addition, this is a traditional measure of portion sizes in British restaurants.

An ounce, as a unit of measurement, is quite rare in Russia and is familiar to a rather narrow circle of people, although the unit of weight, volume, ounce (in Latin uncia, translated as one twelfth in ancient Rome) was used in many countries before they adopted the metric system.

Greetings to my readers! In France, there is the city of Troyes, famous for the architectural monuments of the Middle Ages, offal sausage and low-alcohol drinks.

Troyes is the historical capital of the Champagne region, which gave its name to the sparkling wines that the whole world drinks. And the city itself also gave a name, only not to wine, but to a unit of measurement of the mass of precious metals. A troy ounce of gold in grams is equal to 31.1034768 and is still used in jewelry, banking and cosmetology.

Since ancient times, it has been customary in many places to measure the mass of material in pounds, and these pounds were not identical. The Russian pound was equal to 0.41 kg, and the pound sterling (silver coins) was approximately 0.35 kg. According to one version, it was he who later turned into the British pound - a currency that is now more expensive than the dollar or the euro.

Ancient Rome also had its own pound - libra (327.45 g). An ounce was called the twelfth of it.

The words "Troyes" and "Troyskaya" sound different to the Russian ear, but it is worth looking at the French spelling of the city's name - Troyes - and the similarity becomes obvious.

Kinds of an ounce

  • area: 1 oz - 2400 Roman sq. feet, that is, 29.9 m²;
  • length: 1 oz - 1/12 Roman foot - 0.0246 m;
  • capacity (volume): 1 oz - 1/12 sextarium - 0.0372 cups.

As a measure of mass, the ounce existed in many countries in Europe and beyond and was equal to various amounts of metric grams. Differences have survived to this day.

ounce can mean not only t oz, but also other varieties:

  • fl oz - fluid ounce (there are English and American, both are approximately 30 ml);
  • oz at - Avoirdupois ounce, derived from the trading pound (one oz at - about 28 g).

Conclusion

I hope you understand why the price of an ounce of gold is 31.1034768 times the price of a gram and why it is called "troy"! Stay with me and share new information with your friends. See you!

Gold is a precious metal that has several units of measurement depending on the territory. It is difficult for beginners to navigate the translations of one unit into another. Therefore, people have a question: how much will an ounce of gold weigh in grams? Units of measurement are needed to determine the exact weight of the precious metal. The most popular among them:

  • Grams. This unit of measurement is international, but, unfortunately, it has not taken root in all countries.
  • Ounces. Although the measurement system is quite old, it still exists, especially in relation to the weight of precious metals. And the question of how many grams are in an ounce is still relevant.
  • Carat and fineness are not units of weight. This is just an indicator of the amount of gold in the jewelry, which is expressed as a percentage or carats. Knowing this value and how much the jewelry weighs, you can calculate the mass of pure gold contained in it.

How the amount of gold is measured depends on the tradition. In some countries, ounces are used more when measuring any product, including gold.

Troy ounce

Origin of the ounce

A troy ounce of gold in grams equals 31.1035, which is often rounded up to 31 grams. It so happened that in jewelry, cosmetics and banking, to this day, the value of gold by weight is determined in ounces.

It all started in the XII century in the town of Troyes on the banks of the Seine. It was there that the largest fairs in Europe were held, in which traders and merchants from different countries participated. And therefore, confusion was observed in monetary processes, since exchange rates simply did not exist at that time.

And all the coins, one way or another, were made of precious metals, so the weight of the French livre, which corresponded to one troy pound of silver, was taken as the basis for calculations. Thus, the troy ounce began to gain popularity and soon conquered the world of precious metals: now gold is measured most often with its help. Therefore, the origin of the name has nothing to do with Troy, and writing "Trinity ounce" is incorrect.

A troy ounce in weight is commensurate with one twelfth of an English gold coin pound. 1 ounce of gold weighs the same as some coins:

  • Canadian golden maple leaf;
  • American golden eagle;
  • American golden buffalo;
  • Australian gold bar (this is not an ordinary gold bar).

In addition, we should not forget that, in addition to the troy ounce, there are several more types:

  • an ounce of avoirdupois, its weight is 28.34 grams;
  • pharmacy ounce, which existed in Russia and equated to 26.89 grams;
  • an ounce in grams of Maria Theresa equals 31.10.

Despite the fact that the numbers are close to each other, nevertheless, the troy ounce is the main one in bank calculations for the purchase / sale of gold, it is in it that the precious metal will continue to be measured. Therefore, when buying, it is necessary to clarify the measure of weight, since even the slightest difference in milligrams will affect the cost. The price per ounce of the precious metal is expressed in US dollars, since it is the dollar that is the world reserve currency.

Troy ounce

How is the price of an ounce of gold determined?

The price of gold per ounce is set using the London Fixing. This London time transaction takes place at 10.30 and 15.00 in three currencies: the US dollar, the pound sterling and the euro. But on commodity exchanges everyone uses dollars.

This process is controlled by five of the world's leading banks: Deutsche Bank, Société Générale, HSBC, Scotia Mocatta and Barclays Capital. It is they who analyze the situation on the gold market, compare supply and demand for the precious metal and set the final price.

A fixed price allows the broker to quickly contact buyers and adjust the cost depending on the type of transaction.

The inscription on the bars "oz" or "ounce" is much more common than grams. This is already a world, or royal, measurement quality standard, and it is not so easy to get away from it. Everyone has long been accustomed to using ounces.

In recent years, there has been an upward trend in the price of gold per ounce. The crisis in the economy of many countries is one of the main reasons for the increase in the cost of an ounce of the precious metal, and the process also depends on the policies of large banks and governments. Therefore, according to experts, the next five years there will be an increase in gold prices.

The cost of the precious metal still depends on a combination of many factors and requires an analysis of the market situation. Therefore, investors carefully monitor the course in order to profitably play on gold quotes.

Beginning investors are often confused about weight because they don't know how many grams are in an ounce of gold. Having bought an ingot, a person suddenly receives more metal than he intended to receive. But is it?

This is due to the fact that even in the modern world they use a system such as a troy ounce to determine the weight of gold. And they often confuse this ounce with an ordinary ounce, since grams are used in Russia.

Therefore, when buying in foreign markets, it is imperative to take into account the fact that a troy ounce weighs nine point seven percent more than avoirdupois.

An ounce of avoirdupois

The abbreviation oz or oz at - in the USA and a number of other countries, the basic unit of weight is the pound avoirdupois (453.592 370 g). It consists of 16 oz. The weight of an ounce of avoirdupois is 28.35 g (28.349523125 g).

What is a troy ounce

This is the name of the unit for determining the weight of precious metals, which is included in the Troy system of measures. Referred to as TR.OZ, or troy ounce, or simply ozt. The Romans used this system to measure gold, silver and precious stones. This system includes, among other things, a pound and a grain.

To understand the difference, you need to know what an ounce is.

So: One troy ounce will equal 31.1034768 grams. A pound is equal to 373.2417216g. or twelve troy ounces. A grain is equal to 1 in 480 ounces or 64.79891 milligrams.

One should not confuse the pound in England with the troy pound, since the latter is rarely used today. And you definitely need to separate the ordinary and troy ounce.

In the modern world, it is sometimes still measured in a troy ounce, especially in the financial sector, in jewelry stores, in the pharmacy and cosmetics sector. In order to calculate the metal in cans, a troy ounce is rounded off, and it turns out 31.103 grams.

In this case, it is not clear why to use an outdated system. Why can't you use more modern systems of measures. Let's try to answer this question.

The ancient city of Troy in no way influenced the name of the troy ounce. Troy ounce was named after a small town in France - Troyes. This city became popular in the twelfth century, as fairs were held there with the participation of merchants from all over the world.

Previously, each country used its own system to measure the value of gold, which constantly created difficulties. At first, it was proposed to take the livre as a universal measure, the troy pound was included in the same system. Soon, the troy ounce became the main way to determine the measures of precious metals.
