Density Calculator
Calculates density from mass and volume using SI units.
How it works
Density from mass and volume
Formula and assumptions
Density = mass ÷ volume. With mass in kilograms and volume in cubic metres, the result is kg/m³. Volume must be greater than zero.
Example
Use the sample values, calculate, and change one input at a time.
Frequently asked questions
Are results exact? Results depend on the assumptions and inputs above.
Can I use this for professional decisions? Verify critical results independently.

Frequently asked questions
Can volume be zero?
No. Volume must be greater than zero because density is mass divided by volume.
What should I check before relying on the result?
Confirm the input units and assumptions described above; independently verify safety-critical, medical, financial or professional decisions.
