# What is the metric system known as?

What is the metric system known as? The metric system, also known as the Système international d’unités (SI), was developed in the late 1700s to standardize units of measurement in Europe. The metric system is the primary system of measurement used through much of the world and in science.

Why is the metric system called that? This name was derived from the Greek word, metron, meaning “a measure”. The physical standard representing the metre was to be constructed so that it would equal one ten-millionth of the distance from the North Pole to the equator along the meridian running near Dunkirk in France and Barcelona in Spain.

What are the 3 metric systems?

The metric system uses units such as meter, liter, and gram to measure length, liquid volume, and mass, just as the U.S. customary system uses feet, quarts, and ounces to measure these.

Length Mass Volume
kilometer kilogram dekaliter
centimeter centigram centiliter
millimeter milligram milliliter

Why does the US still use Imperial? In Great Britain, it was Imperial weights and measures and Fahrenheit. “Because Britain had so much influence here in North America, Canada and the United States sided with the Imperial system as well,” said Krashinsky.
