Hectometre

From Wikipedia, the free encyclopedia

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 1 E+2 m (exponential notation) — meaning 100 × 1 m.

nanometre <<< micrometre <<< millimetre < centimetre < decimetre < metre < decametre < hectometre < kilometre

• A more common surface derivative is the hectare, which is a measurement of area with dimensions 1 hectometre by 1 hectometre, hence equating to 1 square hectometre, or 10000 square metres.

• For volumes the hm³ (cubic hectometre) is also used. See cubic metre.
