Density Calculator

Density is mass per unit volume (rho = m/V). A substance with high density has more mass packed into the same space. Lead is denser than wood.

Water at 4 C has a density of 1,000 kg/m3 or 1 g/cm3. At room temperature (25 C) it is approximately 997 kg/m3.

Dry air at sea level and 20 C has a density of approximately 1.2 kg/m3. This is about 830 times less dense than water.

Ice has a density of about 917 kg/m3, which is less than liquid water (1,000 kg/m3). Water expands when it freezes, so the same mass occupies more volume.

Density measurements are used in quality control, material identification, fluid mechanics, buoyancy calculations, and determining concentrations of solutions.
