⚖️ Density Calculator
Calculate density, mass, or volume (d = m/V)
Enter any two values to calculate the third.
How Density Calculation Works
Formula
Density = Mass / Volume (d = m/V)
- 1Enter any two of the three values: mass, volume, or density.
- 2The calculator identifies the missing variable.
- 3Using d = m/V, the missing value is solved algebraically.
- 4If finding mass: m = d × V. If finding volume: V = m / d.
- 5Results are displayed with units and the formula used.

Frequently Asked Questions
What are common density units?
The SI unit is kg/m³. Common alternatives: g/cm³ (1 g/cm³ = 1000 kg/m³), g/mL, and lb/ft³. Water has a density of 1 g/cm³ or 1000 kg/m³.
What is the density of water?
Pure water at 4°C has a density of exactly 1 g/cm³ (1000 kg/m³). This makes water a convenient reference for comparing densities of other materials.
How does temperature affect density?
Most materials become less dense when heated because they expand. Water is unusual — it's densest at 4°C and becomes less dense both above and below this temperature.
