Solve for density, volume, or mass using ρ = m / V, given the other two values.
Density (ρ) is mass per unit volume: ρ = m / V. Rearranged, volume = m / ρ, and mass = ρ × V. Pick which quantity you want to solve for, enter the other two, and this calculator handles the unit conversions internally.
Density values look very different depending on the units used — water is "1" in g/cm³ but "1000" in kg/m³ and about "62.4" in lb/ft³. All three describe the same density; only the units differ. Always double check the unit next to your result, not just the number.
About 1,000 kg/m³ (1 g/cm³, or 62.4 lb/ft³) at 4°C, which is why those numbers show up so often as a sanity check.
Yes — the equation is the same for any material, though gas densities vary much more with temperature and pressure than liquids or solids.
