How to Use This Calculator

Enter your Parameter to Calculate — choose from Calculate Density (ρ) from Mass and Volume, Calculate Mass (m) from Density and Volume, Calculate Volume (V) from Mass and Density, Mass (m) (e.g. 270 in grams), Volume (V) (e.g. 100 in cm³ (mL)), and Density (ρ) / Material Preset (e.g. 2.70 in g/cm³). Verify your units match the formula standard (SI vs imperial) before entering values.

The Formula

Density ρ = Mass m ÷ Volume V

Mass m = Density ρ × Volume V

Volume V = Mass m ÷ Density ρ

SI Unit Conversion: 1 g/cm³ = 1,000 kg/m³

Worked Example

270 grams mass occupying 100 cm³ volume:

Density ρ = 270 / 100 = 2.700 g/cm³.

Understanding Your Result

Density reference values: Water 1.0 g/cm³ (4°C), Aluminum 2.70 g/cm³, Steel 7.85 g/cm³, Copper 8.96 g/cm³, Lead 11.34 g/cm³, Gold 19.32 g/cm³. Objects with density below water (1.0 g/cm³) float; above 1.0 sink. Specific gravity is the ratio of a material's density to water density — dimensionless and equal to the density value in g/cm³ for liquids and solids. Temperature affects density: liquid water is densest at 4°C, and most gases follow PV=nRT for pressure-density relationships.
