The cubic metre is the standard unit of area in the SI metric system other units of volume in the SI system are generally based on the cubic metre with other SI standard prefixes. Note that as the unit is cubed, the factor for the prefix is triple the usual factor. i.e a centimetre is 10-2 metres thus a cubic centimetre is 10-6 cubic metres.
