Does the world use, with the exception of the US, the metric system?

Metric system is one of the most popular measuring systems in the world. It is used in most countries in the world, with a great exception of the United States. However, scientific measurements are also expressed in these units in the US. Is a decimal decimal system with base 10, which facilitates calculations than the US system. Weights are measured in grams, dimensions in meters and volume in liters. The prefixes indicate how much of something is described, and with a few exceptions these prefixes come from the Greek language. For example, a kilogram is 1,000 grams, while a milliliter is 0.001 liters.

Another common measurement is the temperature. The metric system uses the Celsius scale to measure temperature, while the English system uses Fahrenheit. Like all other measurements, temperatures are decimated: freezing water weights measured in Celsius are 0 ° (32 ° F) and boiling point is 100 ° C (212 ° F).

This measurement system has been developed in France in rOce 1791 and was approved by the French government in 1799. They were years of Napoleonic wars and lasted several years because the government had other matters that it considered more urgent. The system then gradually spreads to other countries and has almost become an official US measuring system. However, the United States maintained its loyalty to the old English measuring system, although Britain has accepted the metric system. Only two other countries in the world, Liberia and Myanmar, still accept the "English" measuring system.
