Webspecific gravity, also called relative density, ratio of the density of a substance to that of a standard substance. The usual standard of comparison for solids and liquids is water at 4 °C (39.2 °F), which has a density of 1.0 kg per litre (62.4 pounds per cubic foot). WebThe specific gravity value of any given material is going to be the same in the US, Germany or China! (Also, materials with a specific gravity of less than 1 will float on water) ...
