Glossary

Centimeter (cm)

A centimeter is one hundredth of a meter (1 cm = 10 mm = 0.3937 inch). It is the everyday metric unit for clothing sizes, body measurements, paper formats and small object dimensions. Two and a half centimeters approximate one inch; ninety-one centimeters approximate one yard.

Meter (m)

The meter is the SI base unit of length, defined since 1983 as the distance light travels in vacuum in 1/299,792,458 of a second. One meter equals 100 cm, 1000 mm, 3.2808 ft or 1.0936 yd. It anchors all other metric length units and is the backbone of scientific and engineering measurement worldwide.

Metric system (SI)

The metric system is a decimal system of measurement built around the meter for length, the kilogram for mass and the second for time, with multiples and submultiples expressed as powers of ten (millimeter, centimeter, kilometer). Adopted in France in 1799 and codified internationally as the International System of Units (SI) in 1960, it is now the official measurement system in nearly every country and the standard in science and engineering worldwide.

Imperial / US Customary system

The imperial system is the historical English system of weights and measures whose length units are the inch, foot, yard and mile (12 in = 1 ft, 3 ft = 1 yd, 1,760 yd = 1 mi). Codified by the British Weights and Measures Act of 1824 and aligned with US Customary by the international yard-and-pound agreement of 1959 (1 inch = 25.4 mm exactly), it is still used in the United States, the United Kingdom and a handful of other countries for everyday distances.
