hectometre

A hectometre (American spelling: hectometer, symbol hm) is a somewhat uncommonly used unit of length in the metric system, equal to one hundred metres, the current SI base unit of length. It can be written in scientific notation as (exponential notation) — meaning .nanometre <<<  micrometre <<<  millimetre <  centimetre <  decimetre <  metre <  decametre <  hectometre <  kilometreFor surface the square hectometre (hm2) is a common unit, be it by the name hectare (ha), meaning 100 are (100 a). The are is a measurement of area the size of 1 decametre by 1 decametre, 10 metres by 10 metres. Hence 100 are equals an area with dimensions 100 m by 100 m — 1 hectometre by 1 hectometre, the square hectometre — equalling 10,000  square metres (10,000 m2).For volumes the cubic hectometre (hm3) is also used, 100 m by 100 m by 100 m equalling 1,000,000  cubic metres (1,000,000 m3).
