Density Unit Conversion

Density measures mass per unit volume.

Conversion Factors from kg/m³

  • g/cm³ = kg/m³ / 1,000
  • lb/ft³ = kg/m³ x 0.062428
  • lb/gal = kg/m³ x 0.008345
  • Specific Gravity = kg/m³ / 1,000 (referenced to water)

    • Example Calculation

    Convert 1000 kg/m³ (water).

    1. 01g/cm³ = 1000 / 1000 = 1.0
    2. 02lb/ft³ = 1000 x 0.062428 = 62.428
    3. 03lb/gal = 1000 x 0.008345 = 8.345
    4. 04SG = 1000 / 1000 = 1.0
