What is "decimetre"

Decimeter \Dec"i*me`ter\, Decimetre \Dec"i*me`tre\, n. [F. d['e]cim[`e]tre; pref. d['e]ci- tenth (fr. L. decimus) + m[`e]tre. See Meter.] A measure of length in the metric system; one tenth of a meter, equal to 3.937 inches.

n. (SI-unit deci metre length)

n. a metric unit of length equal to one tenth of a meter [syn: decimeter, dm]

The decimetre (British English) or decimeter ( American English); SI symbol dm) is a unit of length in the metric system, equal to one tenth of a metre (the International System of Units base unit of length), ten centimetres or 1/0.254 (approximately ) inches.

The c is pronounced , unlike in decametre. The common non-SI metric unit of volume, the litre, is defined as one cubic decimetre (however, from 1901 to 1964, there was a slight difference between the two due to the litre being defined with respect to the kilogram rather than the metre).
