Cubic meters to kilograms. Conversion by visible density

Convert m³ to kg and kg to m³ using a visible, editable density. Material condition changes the reference density where relevant.

m³
Dry sand. Construction material.
kg/m³

Density is always visible and editable. Presets are reference values, not hidden assumptions.

Density reference and limitations

Bulk density varies with moisture, grading and compaction. Gas density requires known temperature and pressure. Verify product or supplier data before purchasing or engineering use.

Density is required

Mass equals volume multiplied by density. Volume equals mass divided by density.

Visible assumption

The calculator always shows the density used in kg/m³ and lets you replace it with supplier data.

Important limit

Density can change with moisture, compaction, temperature and pressure. Gas values require stated reference conditions.
