Key Stage 3
Meaning
A micrometre (µm) is a unit of distance equivalent to 1/1000,000th of a metre.
About Micrometres
- Micrometres are shortened to the greek letter µ and a lower case m.
- Micrometres can be used for the size of cells.

Key Stage 4
Meaning
Micrometres (µm) are a unit of distance, displacement and wavelength 1,000,000 times smaller than the SI Unit; the Metre.
About Micrometres
- Micrometres are shortened to µm with the Greek letter µ and a lower case m.
- Micro means one millionth so there are 1,000,000 micrometres in a Metre.
