How much kg in pound, ounce and spool is the history of the matter

To clarify the question of how much kg in the pound, as well as where the name "pound" came from, we will have to go to ancient Rome.

In Rome, used two names for a small weight. To denote the mass of precious metals and already minted coins, the word "libra" was used. The weight of the remaining substances was measured in pounds. Let us examine each of the notations in more detail and find out how many kilos, grams and ounces are in a pound.

Probably, for most of us, the first association with the word "pound" will be "pound sterling". Obviously, the answer to the question "how many kgs in one pound" we are unlikely to find here, but this expression is most often found in everyday life, and it is unfair to deprive it of attention.

The pound sterling is still a monetary unit of Great Britain, some of its former colonies and is denoted by the Latin letter L. It's easy to guess that this is so, because the name comes from the Latin name of the weight measure "libra". As already mentioned, in the Roman Empire, the libra was used to denote weight, mostly precious metals. Libra was 327.45 grams and consisted of 12 ounces, each of which, in turn, was about 27 grams.

Oz is still in the process. They range from 28 (liquid ounce) to 31 grams - this is the so-called "troy ounce". The last in the course of the jewelers and bank workers. Liquid ounce is still in demand with pharmacists and food producers.

The pound sterling initially consisted of one coin of pure silver coins. Then, with the development of the monetary system, banknotes and coins appeared that were not related to the mass of silver that went into their manufacture. The memory of the original Roman source remained only in the form of a designation - the Latin letter L.

In Russia, a spool was attached to the Libra. Probably everyone heard a saying about the fact that the spool is small, but expensive. Indeed, the spool was small and equaled about 4 grams of gold or 1/96 of the ligra. So called and a small gold coin of Kievan Rus.

Pound is another Roman measure of weight used to determine the mass of all other substances. And the answer to the question "how much kg in pound" should be addressed to her.

In Rome, the pound, like the libra, was 327 grams. But in medieval Europe in every more or less significant area, the sovereign gentlemen had the right to set the value of the pound at their own discretion. And it should be noted that they actively used this right, extracting from the answer to the question "how much kg in pound" the maximum benefit for themselves.

In Europe at the end of the eighteenth century, there were at least 100 different pounds. Their values are quite different from each other. For example, the Austrian pound was equal to 560 grams, and the Spanish pound was 450. The French pound, called "livre", was 490 grams and also originally, like the British pound sterling, was used to designate the weight of silver coins. In Russia, the pound was equal to 409 grams, and DI DI created it. Mendeleev.

It is obvious that such a variety of designations of weight measures created a lot of inconvenience. Therefore, the metric system, with its kilograms and grams, was an excellent way out of the situation.

But it would be unfair to forget the pound. Therefore, now, after the adoption of the metric system, you can quite accurately say how much kg in pound. Today, the pound is by default equal to 500 grams.
