==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 [[micrometre]]s in a [[Metre]].
