- Density
- 5 kg/m³
How it works
Volume errors amplify density estimates
If mass is correct but measured volume is 10% too low, calculated density is about 11.1% too high. Recheck small-volume measurements before interpreting a surprising density; the denominator can explain the discrepancy without a different material.
Keeping mass, volume, and density consistent
A sample with mass 54 g and volume 20 cm³ has density 54 ÷ 20 = 2.7 g/cm³, equivalent to 2,700 kg/m³. For this calculator's basic mode, enter 0.054 kg and 0.00002 m³; changing only the unit label would give the wrong answer. Measure mass and volume for the same sample and distinguish material volume from container capacity or a pile's volume including air gaps. The calculator derives density from your measurements; it does not identify a substance or supply its temperature-dependent properties.
Calculate: formula and assumptions
Density = mass/volume.
Use the units printed beside each input. Mass and gravitational weight are different physical quantities.
Find mass or volume: formula and assumptions
Mass=density×volume; volume=mass/density.
All inputs use SI units as labeled.
Worked example
Using the Calculate example:
- Mass (kg)
- 10
- Volume (m³)
- 2
Density = mass/volume.
Example result
Density: 5 kg/m³
These are illustrative inputs. Change the values to explore a different scenario.

Common questions
How does density relate mass to volume?
Density equals mass divided by volume. Rearranging gives mass = density × volume and volume = mass ÷ density.
Can I divide kilograms by cubic centimeters without converting?
Only if the resulting unit is intended. Use the calculator's labeled units consistently; mixing volume scales changes the numerical density.
