Density is defined as the mass per unit volume. The density (ρ) of a substance equals the total mass (m) of that substance divided by the total volume (V) of that substance. The standard SI unit is kilograms per cubic meter (kg/m3) and the standard English unit is pounds mass per cubic foot (lbm/ft3). Most densities are listed at atmospheric pressure (ATM).
The density of gray cast iron is 7150 kg/m3.
