Density

Density measures the amount of mass per unit volume.

Equation

\text{density}=\frac{\text{mass}}{\text{volume}}

\rho=\frac mV

• Density is measured in kilograms per metre cubed (kg\,m^{-3})
• mass is measured in kilograms (kg)
• volume is measured in metres cubed (m^3)

Units

• The SI unit for density is kg\,m^{-3}.
• We can also use g\,cm^{-3}.
