Specific gravity wikipedia
WebSince steel has a specific gravity of roughly 7.8, these materials have a strength-to-weight ratios eight times that of high-strength steels. Strength-to-weight ratios for UHMWPE are about 40% higher than for aramid. The specific weight, γ, of a material is defined as the product of its density, ρ, and the standard gravity, g: The density of the material is defined as mass per unit volume, typically measured in kg/m . The standard gravity is acceleration due to gravity, usually given in m/s , and on Earth usually taken as 9.81 m/s .
