About this calculator
Weight of a load from its volume, to check it against what a trailer, truck or suspended floor can take.
How it’s calculated
Weight = volume × typical density. Real densities vary with moisture and grading, so treat these as planning figures.
Worked example
With these inputs:
- Material
- Gravel
- Volume
- 1.5 m³
- Vehicle payload (optional)
- 1000 kg
the result is:
- Weight
- 2.4 t
- Density
- 1.6 t per m³
- Trips at payload
- 3
Tips from the trade
- A cube of sand or stone weighs about 1.5 to 1.7 tonnes, more than many bakkies and small trailers may carry. Check the payload before you load.
