ρ = m ÷ V
Calculate density from mass and volume
Divide measured mass by measured volume, then convert the result to the density unit you need.

How to calculate density from mass and volume
Density (ρ) = mass (m) ÷ volume (V).
Reverse check: 3 g/cm³ × 200 cm³ = 600 g.
Worked example
For 600 g and 200 cm³: 600 ÷ 200 = 3 g/cm³, exactly 3000 kg/m³.
Keep units paired
A density unit always combines a mass unit with a volume unit. Convert both inputs consistently or let the calculator apply the exact conversions.
