Density of a substance is usually defined and as the mass per unit volume of the substance. In simpler language, how many grams or kilograms or pounds will be the mass of that substance if we take a fixed volume of the substance, say a 1cm cube or 1 litre of it or 1m cube.

Density= Mass / Volume

Mass/Volume = unit i.e. kg/m3
