Density of Graphite

The Density of Graphite constant displays the value of density for graphite (2260 kg/m³). 

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 graphite is 2260 kg/m³.
