How do I convert to kg/m³?

Multiply by 1000. For example, 7.85 equals 7850 kg/m³.

Does density change with temperature?

Yes. Liquids and gases are especially temperature-dependent, and gases also depend strongly on pressure.

Is this logistics density?

No. This is physical mass per volume, not dimensional or freight density.

Density

1,000

Inputs 0.1 kg and 1.000e-4 m³ give 1,000 kg/m³

kg/m³

g/cm³

kg/L

lb/ft³

62.428

Closest material: Water (4 °C) (1,000 kg/m³)

In water: ⬇ sinks (density is 1 times higher than water)

Comparison with known materials

The scale is logarithmic: each division increases the value by 10x. The dashed line marks water density (1000 kg/m³). Left of it floats; right of it sinks.

Density, mass and volume

English density results usually solve any one of density, mass or volume from the other two values.

ρ = \frac{m}{V}

rho is density, m mass and V volume.

m = ρ V, V = \frac{m}{ρ}

Rearranged forms solve for mass or volume.

Material references

Approximate values

Material densities vary with temperature, composition, moisture and pressure. Use manufacturer or lab data for critical work.
