Aggregate Calculator
Work out the volume and estimated weight of aggregate you need.
Volume
1.5m³
- Estimated weight
- 2.4 tonnes
Weight assumes a typical aggregate density of about 1.6 tonnes per cubic metre.

How this is worked out
Volume is length × width × depth. The weight applies a density of 1.6 tonnes per cubic metre.
Worked example
- Length 5 m
- Width 3 m
- Depth 100 mm
5 × 3 × 0.1 = 1.5 m³, and 1.5 × 1.6 = 2.4 tonnes
1.5 m³, weighing about 2.4 tonnes
Assumptions and limits
- 1.6 tonnes per cubic metre is a general figure. Actual density varies with the stone type, grading and moisture.
- The depth entered is the compacted depth, so loose material will heap higher before compaction.
