Origin of centimeter

From the French word centimètre, dating back to 1795–1805. See centi-, meter 1

Explanation

In the metric system, a centimeter is a unit of measurement that's about one-third the size of an inch. There are approximately 30 centimeters in a foot. The word centimeter comes from the French centimètre, a combination of the Latin word for "hundred," centum, and the French mètre. A centimeter is one hundredth of a meter—in other words, there are one hundred centimeters in one meter. In just about every part of the world besides the U.S., this word is spelled centimetre.
