m³
Enter volume in m³.
kg/m³
Enter bulk density in kg/m³.
Conversion

Calculate cubic metres to metric tonnes with explicit inputs and a worked example.

Formula

tonnes = volume × density / 1000

Example Calculation

Example inputs
  • Volume: 2 m³
  • Bulk density: 1500 kg/m³

2 m³ at 1,500 kg/m³ has a mass of 3 t.

Frequently asked questions

How do I use this calculator?

Enter volume, bulk density. The result updates automatically. Use Reset to restore the example values.

What method does it use?

tonnes = volume × density / 1000. Requires the actual bulk density, including moisture and compaction effects.

Why might a rounded result differ?

The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.

Are my inputs saved online?

No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
