Water volume to weight conversion - Aqua-Calc

WebUnit weight of water γ = 9.81 kN/m 3 γ = 9810 N/m 3 γ = 62.4 lb/ft 3 Typical Values of Unit Weight for Soils Densities of Soil The terms density and unit weight are used interchangeably in soil mechanics. Though not critical, it is important that we know it. WebTaking the standard density of water at 4°C to be 997 kg/m 3 and multiplying by the standard gravitational acceleration of 9.807 m/s 2, the specific weight of water comes out to be 9777.579 N/m 3. Oftentimes, this value is simply rounded to 1×10 3 N/m 3.
