Many everyday calculations involve measurements of some kind: for example, lengths, times, amount of money and so on.

In the UK, both the metric and imperial systems of measurements are used.

The different units for the same type of quantity are related to each other via power of ten:

The imperial system, the units are related in different ways: for example, 1 stone is the same as 14 pounds.

This module mostly uses the standard metric system known as the système community d'Unitès (SI units).

There are seven base SI units, from which all the other are derived.

The base units used most frequently in the module are the metres and kilograms and the second.

Prefixes are used to indicate smaller or larger units, for example, millimetres, centimetres, metres and kilometres are all used to measure length.
