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.

Converting to Micrometres

Unit To convert Micrometres
1 Megametre (1Mm) Convert to micrometres x1000,000,000,000. 1000,000,000,000µm
1 kilometre (1km) Convert to micrometres x1000,000,000. 1000,000,000µm
1 metre (1m) Convert to micrometres x1000,000. 1,000,000µm
1 millimetre 1(mm) Convert to micrometres x1,000. 1000µm
1 micrometre 1(µm) Convert to micrometres x1. 1µm
1 centimetre 1(cm) Convert to micrometres x10,000. 10,000µm

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.
