What Is The Specific Weight?FormulasRelationship Wth

2021524 Specific gravity is the relationship between the weight and volume of a substance Since the weight of an object is the extent to which the attraction of the Earth acts on it and at the same time the volume is the surface that said object occupies the specific weight constitutes the relationship between both properties expressed in Newtons
