Density Converter

Convert between all common density units including kg/m³, g/cm³, g/mL, kg/L, lb/ft³, and lb/in³. Essential for chemistry, physics, materials science, and engineering.

Density is the mass per unit volume of a substance. Different fields and regions use different density units.

Key Conversion Factors:

  • 1 g/cm³ = 1,000 kg/m³ = 1 g/mL = 1 kg/L
  • 1 lb/ft³ = 16.018 kg/m³
  • 1 lb/in³ = 27,680 kg/m³

Common Densities:

  • Water: 1,000 kg/m³ (1 g/cm³) at 4°C
  • Air: 1.225 kg/m³ at sea level
  • Steel: 7,800-8,050 kg/m³
  • Aluminum: 2,700 kg/m³
  • Gold: 19,300 kg/m³
  • Wood (oak): 600-900 kg/m³

Density determines whether an object floats or sinks. Objects with density less than water (1 g/cm³) float in water.
