Common Densities (kg/m³)
How this works
Density = Mass / Volume. All inputs are converted to SI (kg, m³, kg/m³) before calculation, then displayed in the selected units.
If you provide mass and volume, density is calculated. If you provide mass and density, volume is solved. If you provide volume and density, mass is solved.

Density is the mass per unit volume of a substance, expressed as ρ = m / V. It is one of the most fundamental physical properties in engineering, used in fluid mechanics, materials science, drilling operations, and process design. In petroleum engineering, fluid density determines hydrostatic pressure, buoyancy, and flow behavior.
This calculator handles all three solve modes: given mass and volume, compute density; given mass and density, compute volume; given volume and density, compute mass. All conversions are handled automatically. Built by Groundwork Analytics.
