metre

n. (British spelling for meter) basic unit of length in the metric system, one hundred centimeters, 39.37 inches; definite measurement; poetic measure; rhythm (in music); instrument that automatically measures quantities of substances (gas, water, or electricity)

The metre or meter(symbol: m) is the fundamental unit of length in the International System of Units (SI). The metre was originally defined by a prototype object meant to represent the distance between the poles and the Equator. Today, it is defined as of a light-second.Because it is the base unit of length in the SI, all SI units which involve length (such as area or speed) are defined relative to the metre. Additionally, due to the metre being the only SI base unit used to measure a vector (e.g. displacement), all vector units are defined relative to the metre. However, decimal multiples and submultiples of the metre— such as  kilometre (1000 metres) and centimetre (0.01 metres)— can be formed by adding  SI prefixes to metre (see the table below).
