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).
