Density Calculator
Enter any mass and volume to get density in your choice of kg/m³, g/cm³ or lb/ft³, converted automatically between unit systems. A comparison table shows where your material sits among water, metals, woods and gases.

Formula
ρ = m ÷ V (density = mass ÷ volume)
- • Convert the mass to kilograms and the volume to cubic meters.
- • Divide mass by volume → density in kg/m³.
- • Convert: g/cm³ = kg/m³ ÷ 1000; lb/ft³ = kg/m³ × 0.062428.
Pro tips
- • Water is the benchmark: 1000 kg/m³ = 1 g/cm³ = 62.43 lb/ft³ at 4 °C.
- • Specific gravity is just density ÷ 1000 (kg/m³) — dimensionless, so units cancel.
- • Temperature changes density (warm water is less dense) — cite the temperature for lab work.
