A decimetre (American spelling: decimeter, symbol dm) is a unit of length in the metric system, equal to one tenth of a metre, the current SI base unit of length. It can be written in scientific notations as 100×10-3 m (engineering notation) or 1 E-1 m (exponential notation) — meaning 100 × 1 mm or 1 m / 10 respectively. The c is pronounced as /s/, unlike in decametre. nanometre <<< micrometre <<< millimetre < centimetre < decimetre < metre < decametre < hectometre < kilometre
