BEHIND THE NUMBERS

Iron (elemental reference): density reference

Reported density: 7.87 g/cm³. Review phase, composition, room-temperature scope and limitations before estimating mass.

Reported property

Density: 7.87 g/cm³, equivalent to 7870.00 kg/m³ by SI unit scaling. Source display precision: 3 significant digits.

Scope and conditions

Elemental iron reference; not a certified commercial grade, alloy, oxide, powder or porous bulk density.

Phase: Solid (RSC state-at-20°C field). 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, measurement method and uncertainty: unspecified by the cited density reference.

Use for a mass estimate

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.

Limitations

Use the reported 3 significant digits as a ceiling for display precision; the user volume may justify fewer. Actual density can differ with composition, temperature, porosity and processing. This reference does not establish material suitability, structural capacity, handling requirements or safety.

  • 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.
