Density Unit Knowledge

Density Basics

Density is mass per unit volume. The SI unit is kg/m³. Water has a density of 1,000 kg/m³ (or 1 g/cm³). Materials denser than water sink
less dense materials float.

Common Material Densities

Water: 1,000 kg/m³
Air: 1.225 kg/m³
Steel: 7,850 kg/m³
Aluminum: 2,700 kg/m³
Gold: 19,320 kg/m³
Wood (varies): 400–900 kg/m³
Concrete: 2,300 kg/m³.

Density Units Comparison

1 g/cm³ = 1,000 kg/m³ = 1 kg/L. Iron has density of about 7.87 g/cm³. Lead is 11.34 g/cm³. Mercury (liquid) is 13.534 g/cm³, which is why it sinks most metals.
