==Key Stage 4==
===Meaning===
'''Megajoules''' ('''MJ''') are a [[unit]] of [[energy]] 1,000,000 times larger than the [[SI Unit]] of the [[joules]].
===About Megajoules===
: '''Megajoules''' are shortened to '''MJ''' with an upper case M and an upper case J.
: [[Mega]] means one million so there are 1,000,000 [[Joule]]s in a [[megajoule]].
