Enter Mass and Volume
Select whether to calculate density, mass, or volume based on what values you know.
Input the measured values for your calculation. Use consistent units (kg, m³).
The calculator uses ρ = m/V to determine density, or rearranged formulas for mass/volume.
Check your calculated value and specific gravity relative to water.
Compare your result with known material densities to verify or identify materials.
Relate ρ, m, and V quickly. Includes specific gravity to compare against water.
Solve for density, mass, or volume with unit conversions.
Any variable from the other two.
kg/m³, g/cm³, lb/ft³.

Important: This density calculator is designed for educational and general material analysis purposes using standard density relationships and typical material properties under standard conditions. While calculations are mathematically accurate for basic density determinations, actual material density varies significantly with temperature, pressure, composition, impurities, and processing conditions that are not accounted for in simplified density calculations. For materials engineering, quality control, process design, or any application requiring precise density values, use appropriate measurement techniques, consider environmental conditions, and consult qualified materials engineers or chemists who can account for the specific factors affecting density in your particular application and operating environment.
Materials lighter than water. Common in woods, plastics, oils, and gases. These materials will float on water.
Similar to water density. Common in biological materials, some solutions, and ice.
Denser than water but lighter than most metals. Common in rocks, concrete, and some alloys.
Very dense materials like metals (steel, copper, lead). These sink rapidly in water and are typically strong materials.
