Water - Density and Specific Weight

Density and specific weight of water at temperatures ranging 0 - 100 oC (32 - 212 oF) - Imperial and SI Units

At aprox. 4oC (39.2oF) pure water has it's highest density 1000 kg/m3 (weight or mass).

  • 1 g/cm3 = 1 g/ml = 1 kg/litre = 1000 kg/m3 = 1 tonne/m3 = 62.4 lb/ft3 = 8.34 lb/gallon.

Weight per US gallon is based on 7.48 gallons per cubic foot.

  • 1 Gallon (U.S.) = 3.785x10-3 m3 = 3.785 dm3 (liter) = 0.13368 ft3 = 4.951x10-3 yd3 = 0.8327 Imp. gal (UK)
