# 1 centimetre: how many millimetres, metres, kilometres?

 0 661

A centimetre is a unit of length derived from a metre: one of the basic units in SI (metric) system. Also, it was one of three basic units of CGS (centimetre-gram-second), the obsolete variant of the metric system.

1 centimetre = 10 millimetres = 0.01 metre = 0.00001 kilometres

ca. 2.54 centimetres = 1 inch

As it was mentioned above, a centimetre is a derivative of a metre. The prefix centi- is one of the metric prefixes (unit prefixes which modify the value of the basic unit), which means ‘divided by 100’. And so, a centimetre is 0.01 metre.

Below you will find a list of metric prefixes for other units derived from a metre:

Centimetres are used for measuring rainfall. Meteorologists use a cylindrical instrument called a rain gauge to catch rain water and, after some time, they measure the height of the accumulated water. The reading of the results is typically done in centimetres.

 Technically Scotland doesn't count because they abolished the use of counties, hence why Inverness shire is not on the list.
