About this calculator
Density is how much mass is packed into a volume: ρ = m / V. Choose which quantity to solve for and enter the other two. Mass is in grams, volume in cubic centimetres (equal to millilitres) and density in g/cm³, so water comes out at about 1.
Frequently asked questions
What is the density formula?
Density equals mass divided by volume, ρ = m / V. Rearranged, mass = ρ × V and volume = m / ρ.
What units does this use?
Mass in grams and volume in cubic centimetres (1 cm³ = 1 mL) give density in g/cm³. Pure water is about 1 g/cm³, so denser-than-water materials read above 1.
