Glossary

Mile (mi)

A statute mile is 5,280 feet or exactly 1,609.344 m. It is the road-distance unit in the United States, the United Kingdom and a few other countries; speed limits there are posted in miles per hour. Do not confuse with the nautical mile, which is longer and based on Earth's arc.

Kilometer (km)

A kilometer is one thousand meters (1 km = 0.6214 mile = 0.5400 nautical mile). It is the standard road-distance unit everywhere except the United States, the United Kingdom and a handful of other countries. Marathon distances, highway speeds and geographic distances on most maps use kilometers.

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.
