==Key Stage 4==
===Meaning===
'''Nanojoules''' ('''µJ''') are a [[unit]] of [[energy]] 1,000,000,000 times smaller than the [[SI Unit]] of the [[joules]].
===About Microjoules===
: '''Nanojoules''' are shortened to '''nJ''' with a lower case n and an upper case J.
: [[Nano]] means one billionth so there are 1,000,000,000 [[nanojoule]]s in a [[Joule]].
