For the units just use the phrase &quot;<b>K</b>ing <b>H</b>enry <b>D</b>oesn't <b>M</b>ind <b>D</b>rinking <b>C</b>hocolate <b>M</b>ilk&quot; (Kilometres, Hectometres, Decametres, Metres, Decimetres, Centimetres, and Millimetres). That's from highest to lowest. So when you want to convert to just divide or multiply by 10 for each unit you're jumping. So, for examples, 1 centimetre is 10 millimetres (1*10) and 100 decametres is 1 kilometre (100/(10*10)). Easy.
