Units of Measurement/Density

Density is the mass per unit volume of a substance. The formula for density is: D=m/v.

The unit for mass is kilograms (kg)/grams (g) and volume in centimetres cubed (cm3) or metres cubed (m3). Example 1. A stone of mass 20 kg with volume 4 cm3 calculate its density. density = mass/volume = 20kg/4cm3 = 5kg/cm3
