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