Density Calculator – Instantly Calculate Density from Mass and Volume
Understanding density is crucial in science, engineering, and everyday life. Whether you're a student conducting a lab experiment, an engineer designing materials, or a DIY enthusiast curious about substances, a reliable Density Calculator can save time and ensure accuracy.
What Is Density?
Density is a physical property that describes how much mass is contained in a given volume.
Density (D) = Mass (M) / Volume (V)
The SI unit is kg/m³, though g/cm³ and g/mL are common in chemistry.
How to Use
- Enter the mass (M) in the first field.
- Enter the volume (V) in the second field.
- Click Calculate to get density.
- Click Copy Result to copy the output.
Rearranging for Mass or Volume
- Find Mass: M = D × V
- Find Volume: V = M / D
Example Calculations
Mass = 250 g, Volume = 125 cm³ → D = 250 / 125 = 2 g/cm³
Mass = 5 kg, Volume = 0.002 m³ → D = 5 / 0.002 = 2500 kg/m³
Density of Common Substances
- Water: 1 g/cm³
- Ice: 0.92 g/cm³
- Aluminum: 2.7 g/cm³
- Iron: 7.87 g/cm³
- Gold: 19.3 g/cm³
- Air (sea level): ~0.001225 g/cm³
Frequently Asked Questions
What is the density of water?
1 g/cm³ or 1000 kg/m³ at 4°C.
Can I use any units?
Yes — the result will be in whatever units you enter (e.g., kg and m³ give kg/m³).
What if volume is zero?
The calculator returns an error — dividing by zero is undefined.
What is specific gravity?
Density relative to water (1 g/cm³). Gold's specific gravity = 19.3.
Does temperature affect density?
Yes — especially for gases. Use values measured at the same temperature.
