Hectometre

The hectometre, (SI symbol: hm^[1]), spelt hectometer in American and Philippine English, 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).
