Metric System of Measurements

                Length                                       Area

      10 millimetres = 1 centimetre              100 sq. mm     = 1 sq. cm

      10 centimetres = 1 decimeter             10 000 sq. cm     = 1 sq. metre

      10 decimetres  = 1 metre                   100 sq. metres = 1 are

      10 metres      = 1 decametre              100 ares       = 1 hectare

      10 decametres  = 1 hectometre           10 000 sq. metres = 1 hectare

      10 hectometres = 1 kilometre              100 hectares   = 1 sq. kilometre

      1000 metres      = 1 kilometre          1 000 000 sq. metres = 1 sq. kilometre

 

               Volume                                        Capacity

   1000 cu. mm = 1 cu. cm                         10 millilitres = 1 centilitre

   1000 cu. cm = 1 cu. decimetre                10 centilitree = 1 decilitre

   1000 cu. dm = 1 cu. metre                      10 decilitres  = 1 litre

   1 million cu. cm = 1 cu. metre                  1000 litres      = 1 cu. metre

 

                                      Mass

                               1000 grams     = 1 kilogram

                               1000 kilograms = 1 tonne

The distinction between 'Volume' and 'Capacity' is artificial and kept here only for historic reasons.

A millitre is a cubic centimetre and a cubic decimetre is a litre. But see under 'Volume' for problems with the litre.
