How it is computed
Densities are typical values near 20 °C from standard references. lb/ft³ = kg/m³ ÷ 16.0185 and g/cm³ = kg/m³ ÷ 1,000. Alloys, woods and stone vary by grade, moisture and porosity, so treat them as averages.
FAQ
How do I get the weight of an object?+
Multiply its volume by the density: 0.01 m³ of steel × 7,850 kg/m³ ≈ 78.5 kg. The density calculator does it in any unit.
What is specific gravity?+
Density divided by the density of water, about the same number as the g/cm³ column.
