Density / Mass / Volume Calculator
ρ = m / V • m = ρ × V • V = m / ρ
Only the logical input fields stay visible for the selected equation.
Quick summary
Choose what to solve for, enter the required values, then click Calculate.
Density must be greater than 0.
Mass must be 0 or greater.
Volume must be greater than 0.
Results
Density
— kg/m³
Mass
— kg
Volume
— m³
All results are shown in standard SI units.
Use this Density Calculator to solve for density, mass, or volume when the other two values are known.
Calculation Methods
Density = Mass ÷ Volume
ρ = m ÷ V
Rearranged:
Mass = Density × Volume
Volume = Mass ÷ Density
Example
If an object has a mass of 5 kg and a volume of 0.002 m³:
Density = 5 ÷ 0.002
Density = 2,500 kg/m³
Important Note
Use compatible mass, volume, and density units. Density can vary with temperature, pressure, composition, and physical state, particularly for gases and liquids.
