List two non-SI units for volume, and explain how they relate to the cubic centimeter.

The two non-SI units of volume are cubic feet (cu. ft) and gallon (gal). Cubic feet is mostly used while measuring gases and gallon is mainly used to measure liquids. These two non-SI units are definitely popular units of measurement.

The relation between cubic feet and cubic centimetre can be deduced by

1 foot = 2.54 cm X 12 inch/ft

= 30.48 cm

So

1 cubic foot = 3 * (30.48 cm)

= 28317 cubic centimetre

The relation between gallon and cubic centemetre can be deduced by

1 gallon = 3.785 litres X 1000 cc/L

= 3785 cubic centemetre.
