Sense: noun/1
Metre, centimetre, and kilometre are all metric units of length. A metre is the base unit (roughly the height of a doorknob). A centimetre is one hundredth of a metre (about the width of a fingernail) — use it for small objects like a pen or a finger. A kilometre is 1,000 metres (about 0.6 miles) — use it for long distances between towns. Yard and foot belong to the imperial system: a yard is slightly shorter than a metre (0.91 m), while a foot is about 30 cm. The metre is the international standard and is used in science and most countries worldwide; centimetres and kilometres are simply its subdivisions or multiples for different scales.

Etymology
The word metre entered English in the late 1700s from French mètre, which was coined from Greek metron (μέτρον) meaning 'a measure.' The length unit was adopted during the French Revolution as one ten-millionth of the distance from the equator to the North Pole along the Paris meridian. The poetic and musical senses arrived in English much earlier (via Old French and Latin) from the same Greek root metron, reflecting the idea that poetry and music both have 'measured' patterns. The spelling 'metre' is the British preference, while American English uses 'meter' for all senses.
