A kilometre is one thousand metres! so km m or m kmA millimetre is a thousandth of a metre! so mm m or m mm A centimetre is one hundredth of a metre! so cm m or m cm Think about how to use this to help you change to different units ... and back again .... mm cm m km mm cm m km1000÷ 1000÷ 10001000÷ 100100÷ 10÷ 100÷ 1000100010010
