==Key Stage 4==
===Meaning===
'''Megametres''' ('''Mm''') are a [[unit]] of [[distance]], [[displacement]] and [[wavelength]] 1,000,000 times larger than the [[SI Unit]]; the [[Metre]].
===About Megametres===
: '''Megametres''' are shortened to '''Mm''' with an upper case M and a lower case m.
: [[Mega]] means one million so there are 1,000,000 [[Metre]]s in a [[megametre]].
