Units Measure

Units Measure Book Reference

Measurement is a process that uses numbers to describe a physical quantity based on what we can observe. This is done to be able to compare them to each other. We can measure how big things are, how warm they are, how heavy they are, and lots of other features as well. Units of Measurement provide standards for our comparisons, so that the numbers from our measurements refer to the same thing.

For example, the metre is a standard unit to measure length. Before 1982, it was defined as the distance between two markers on a special rod. Now scientists define the metre by using the speed of light. Saying something has a length of 2 metres means that it is exactly twice as long as that rod used to define the metre, or that light takes twice the time defined for a metre to travel that distance.
