Rock Tonnage & Volume Calculator

STEP BY STEP

How to use rock tonnage & volume calculator

1. Enter your measured values in the displayed units.
2. Review the calculation: Mass in tonnes = volume in m³ × density in t/m³.
3. Read the result and compare with the example.

WHEN IT HELPS

Common uses

• Check the worked example: 250 m³ at 2.7 t/m³ gives 675 t.

IN PRACTICE

Example

250 m³ at 2.7 t/m³ gives 675 t.

GOOD TO KNOW

Which volume basis is used?

Match density to the volume basis: in-situ, loose or compacted. This tool does not assume a swell factor.
