A millimetre is the smallest metric unit used by most people to measure the length of something. You would commonly use millimetres to measure items that are really small or need to be measured very accurately; for example, the dimensions of a washing machine is usually measured in millimetres.

Centimetres and metres are also commonly used to measure items for everyday tasks.

Kilometres would be used to measure the distance between places. A runner may clock the distance that they have run in kilometres.
