# 450 kg is how many pounds

## How many kg in pounds, ounces and spool - background

To clarify the question of how many kg in a pound, as well as in which everyone gave the name "pound", we will go to ancient Rome.

In Rome it was used two names for light weight. I use the word "scales" to describe the mass of precious metals and coins already minted. Weight remaining substances were measured in pounds. Let's look at each of the symbols and find out how much a pound is in kilograms, grams, and ounces.

Probably most of us the first association with the word "pound" becomes "pound". Obviously, the answer to the question, "How many kilograms per pound," we are unlikely to find here, is an expression we encounter more often and wrongly in everyday life.

Pound sterling is still the currency unit of the United Kingdom, some of its former colonies, and is denoted by the Latin letter L. It is easy to guess that this is because the name is derived from the Latin name that measures weight, "Libra". As already mentioned in the Roman libra, used to indicate weight, especially precious metal. The scales equal 327.45 grams and were made up of 12 ounces, each of which in turn was approximately 27 grams.

Oz is still on trend. They range from 28 (fluid ounce) to 31 grams - the so-called "troy ounce." Load in the course of jewelers and bankers. Fluid ounces are now required by pharmacists and food manufacturers.

Pound was originally a libra coin made of pure silver. Then with the development of the monetary system, banknotes and coins were in no way connected with the bulk of silver that went to their production. The memory of a novel remained the primary source, except perhaps in the form of notation - the Latin letters L.

In Russia it was tied with the Libre coil. Everyone has probably heard the word from that little reel, but streets. In fact, the sled was small, about 4 grams of gold, or 1/96 of the scales. They called and a small gold coin of Kievan Rus.

Pound - another novel measure of weight used for determining the mass of all other substances. And the answer to the question "how many kg in the pound" should be addressed to them.

In Rome, the pound, as well as Libra, it was equal to 327 grams. But in medieval Europe, each more or less significant area, the sovereign lords had the right to determine the value of the pound at their own discretion. And it should be noted that they are actively exercising this right, drawing the answer to the question "how many kg in the pound" of the maximum benefit for themselves.

In Europe in the late eighteenth century there were no fewer than 100 different pounds. Their values ​​are sufficiently different from one another. For example, the Austrian pound was equal to 560 grams, and Spanish - French called 450 lb "livre", amounted to 490 grams and was also originally used as the British pound sterling to refer to measures by weight of the silver. In Russia, the pound is equal to 409 grams, and its standard was established by DI Mendeleev.

It is obvious that such a variety of weight measures creates a lot of inconvenience. Hence the metric system, with its kilograms and grams, became a great way to get out.

But it would be unfair to forget about the pound. So now, having adopted the metric system, you can definitely tell how many kg per pound. Today pounds are equated to 500 grams by default.
