Many of you have certainly heard the word "ounce".But everyone knows what it means?This is an obsolete measure of weight and not only.Incidentally, this concept has a rich history.And in some sectors of the economy without this measure you can not manage.So how many grams 1 ounce weighs?
word
Without a doubt, is a term of Latin origin.In ancient Rome, the so-called one-twelfth of Libra - the main measure of weight.However, not only its weight was measured.In general, it may seem that the word is very fond of the Romans.
They often say: "I went to four ounces of the way .." or "I read the book three ounces."What does this mean?Is is possible to measure the distance with the help of weights?No of course.Ounce - this is one-twelfth of anything.Well, or one-tenth or thirteenth - depending on the country and time.So what does she even measured?And how?Also ounce in ancient Rome called the coin.She put in the minting of one point.The coin is, of course, a small denomination.Making it an alloy of tin, copper and lead.They called and some Spanish (doubloons) and Chinese gold coins.
measures
So ounce - is, of course, not only the standard weight.It is also a two-unit volume and one - force.In general, to identify the mass, there is a few ounces.The Romans, as has been said above, it is also used to measure length, area, capacity, and even the value of the inheritance.For example, 1 oz length in ancient Rome was equal to 0.0246 meters.A surface (area) there uger measured.Accordingly, one-twelfth of his - 1 ounce - is 209.91 meters.
Species
ancient Roman measure of weight - 1 oz (one twelfth of Libra) is equal to 28.34 g seems quite a bit.But it is also divided into shares: semuntsii, sitsilikusy, scruple and silikvy.The latter was already oz 144.
Prior to the metric system was an ounce of common everywhere in Europe.It is used today.However, not even all measures of weight with the same name.Let us dwell on the most famous.
troy ounce
About this unit of measure to say, probably, all possible.Currently, it is used for weighing precious metals.Also, a unit in the last trade on special exchanges.
There the price of gold and other precious metals is determined by the rate per troy ounce.The weight of it in terms of the metric system of approximately 31,103 grams.As you can see, it is different from ordinary oz.Once it is used in jewelry and banking.It is measured as the weight and valuable ingredients in cosmetics.But it appeared?
emergence of this term can be traced to the thirteenth century AD.Some people seem surprising, but this measure is not related to the legendary city of Troy.And it appeared in the French Troyes.There's a time (12-13 century, and according to some sources - from the 5th century) have become very popular three-month fair, which attracts people from many European countries.The abundance of various currencies (in France, then almost every city had its own money) and measures the weights (for each product exist site) created confusion in the trade, but because after a while it was decided to take as a reference the French livre, which contained a pound of silver.
1 troy ounce, respectively, is one-twelfth of that measure.It is believed that this was not without the participation of the French crown.In any case, the unit seemed very comfortable.After all, this coin weighed exactly pound.And while money is valued for its weight.This precious metal later they were replaced by nickel or copper.However, the kings came and went.And control of chasers, which were many, have not always been at a sufficient level.So in the French silver coins became smaller.Very often, precious coins generally cut to get silver or gold.Therefore, it was necessary to introduce a standard coinage with a clear boundary.Over time, gold and silver, of course, dramatically escalated in the value of the world's denomination coins.And they have practically ceased to be added.
Coins
At present, banks in many countries continue vypuskayutsya gold coins.And they acquire not only for private collections.So people can invest and keep their money in gold.In this sense, it is the equivalent of gold bullion.Most of these coins contains just an ounce of gold:
1. Australian gold bullion (coins).
2. The Austrian Philharmonic.
3. The American Gold Buffalo.
4. American Gold Eagle.
5. Canadian gold maple leaf.
6. China Panda.
7. The South African Krugerrand.
They all have a corresponding inscription.And, of course, not all of them weigh exactly ounce.They may contain other metals.But troy ounce of gold, silver or platinum they be required.Incidentally, buying precious metals via the Internet, be careful: in some units there is specified weight.After all, an ounce of averdyupua (it is now the most commonly used in the trade) troy easier.As you can see, it's old, it would seem, a measure of weight and did not think to give its position in this area grams and kilograms.Perhaps this is because such a significant items such as gold, for example, must be measured as significant values.Even simpler to manufacture ingots weighing 31 grams rather than odnogrammovye.In general, the example of the coin can be excellent and available to answer the question: "An ounce - gram of gold is how many?"
American system of measures
In the United States, and to this day is used to measure the weight of pounds.And along with them, hence, the ounce.But then again, are not the same as everywhere else.
Averdyupua or so-called business ounce.Applied to the sales of goods by weight.In the metric system, its value is equal to 28.349 g
US fluid ounce is used to measure volume.It is equal to about 29.537 mL.When referring to the volume of packages with food for convenience, it equates to 30 milliliters.The English, by the way, has a fluid ounce.Its volume is equal to 28.413 ml.
European measures weight
Like many others, an ounce was borrowed from the Roman Empire to almost all the peoples of Europe.And widely used until the introduction of the eighteenth century the metric system.For example, in Germany it was one-sixteenth share of trading the pound.Also it has been used in medicine, which is equal to 1/12 of the small weight of pharmacy.She measured the weight of the preparation of medicines.The so-called chemist ounce and remained until now.The Germans took over this system and Russia.She weighed 25 to 35 g - depending on the country where it was used.Apply it sometimes today.Therefore, buying some foreign medicine at the pharmacy, it is important to know how many grams in 1 ounce.Overdose does not need you or your doctor.
In the Netherlands, too, used the ounce.Even when in 1820 moved to the new system, the Dutch kept their ounce to indicate its weight one hundred grams.
not lag behind other countries in Europe.In Italy, the Roman pound was 12 ounces, and in Spain and Portugal to 16, respectively, in Castilian Libre and cooperative.
In England there is already mentioned above troy ounce, chemist and trading.They were the shares of similar pounds.But if Troy and chemist - is 1/12, the trading amounted to one-sixteenth of an ounce.
And once again about the coins.In Sicily until 1860 he was in the course of an ounce.It is equal to two and a half crowns, three ducats.And was the equivalent of one hundred and twenty-three Italian lyres new time.
on other continents
Besides America, where ounce caught on in the United States, she has found its application in Africa.In the north of the continent called her ukkiya.For example, in Algeria match 34.13 grams, Tunisia - 31.68, in Egypt - 37.068 and 1 ounce of Tripoli weighed 30.02 g
In conclusion
So we know what is equal to 1 ounce.And it appeared in ancient Rome.There it was used to measure not only the weight, it was more the mathematical symbol.From there she went to conquer the world.Largely ounce anticipated the metric system in Europe.Only instead of one-tenth of ancient Rome there was 1/12.Perhaps this was due to the mythology.In life, then the figure of twelve people was quite symbolic.
Next ounce boldly walked across Europe, changing a little bit, depending on the country.Then it was replaced more than comfortable kilograms and grams.But a troy ounce and averdyupua reached to the present day.Probably because that good is bad is forgotten.After all, it was the first standard measure of weight in emerging Europe.And largely because of it economies are able to develop properly.She has facilitated trade and became a measure of the value at the time the goods - gold.
