Iron (elemental reference) mass calculator
Estimate mass from net solid volume using the published elemental iron density of 7.87 g/cm³.
Reference calculation or estimate for example inputs; assumptions and limitations apply.

What to enter
| Input | Meaning and units |
|---|---|
| Net solid material volume (m³) | Exclude holes and voids. This is not powder bulk volume, package volume or an alloy-grade specification. |
Understanding your result
The result is estimated mass for the entered net solid volume using this elemental reference density. At 0.001 m^3 (one litre of solid material), the reference mass is 7.87000 kg. It is not force/weight in newtons, shipping gross mass or a strength/design result.
Common mistakes
- Using this elemental density for an alloy or commercial grade without checking its datasheet.
- Using outside/envelope volume for a hollow or porous object instead of net solid material volume.
- Entering centimetres as metres; cubic unit conversion must be applied before density multiplication.
Check your calculation
- Use the worked example as a known reference case, then change one input at a time and check the direction and units of the response.

How much mass does this net volume of elemental iron represent?
The result is estimated mass for the entered net solid volume using this elemental reference density. At 0.001 m^3 (one litre of solid material), the reference mass is 7.87000 kg. It is not force/weight in newtons, shipping gross mass or a strength/design result.
Common uses
- Estimate reference mass from measured net solid volume.
- Compare units and the reported elemental density with an actual material datasheet.
How it works
Mass = net solid volume × reference density. Use 7870.00 kg/m³, derived from the published 7.87 g/cm³. Elemental iron reference; not a certified commercial grade, alloy, oxide, powder or porous bulk density. Room temperature, as stated in RSC density glossary. Exact numerical density temperature unspecified; the separate state-at-20°C field is not a density measurement temperature. Pressure, purity and uncertainty are not stated by the reference. Convert volume to m³ first and exclude holes/voids from a solid object's material volume.
Worked example
A net volume of 0.001 m³ (one litre of solid material) gives approximately 7.87000 kg using this reference.
