==Key Stage 4==
===Meaning===
'''Kilowatts''' ('''kJ''') are a [[unit]] of [[power]] 1,000 times larger than the [[SI Unit]] of the [[Joule]]s.
===About Kilowatts===
: '''Kilowatts''' are shortened to '''kJ''' with a lower case k and an upper case J.
: [[Kilo]] means one thousand so there are 1,000 [[Watt]]s in a [[kilowatt]].
===Converting to Kilowatts===
