==Key Stage 4==
===Meaning===
'''Milliwatts''' ('''mJ''') are a [[unit]] of [[power]] 1,000 times smaller than the [[SI Unit]]; the [[Watt]].
===About Milliwatts===
: '''Milliwatts''' are shortened to '''mJ''' with a lower case m and an upper case J.
: [[Milli]] means one thousandth so there are 1,000 [[milliwatt]]s in a [[Watt]].
===Converting to Milliwatts===
