The hectometre (SI symbol: hm), spelled hectometer in American English, is a unit of length in the International System of Units (SI), equal to one hundred metres[1] and to one tenth of a kilometre. The word comes from a combination of "metre" and the SI prefix "hecto-", meaning "hundred".[2] It is not commonly used in English.[citation needed] A football field (either soccer or American football) is approximately 1 hectometre in length.[3][4] The hectare (ha), a common metric unit for land area, is equal to one square hectometre (hm2).
The hectometre has sometimes been used for expressing the distance to a target in warfare.[5][6][7]
