- Multiply the volume by the bulk density, 1720 kg per cubic metre for stone dust, to get a weight.
- Divide the weight by your supplier's ton or cubic yard to get what to order, and round up. Suppliers do not sell part bags.
- Add 10 percent. Covers settlement, uneven ground and the material lost around the edges. A second delivery for half a yard costs more than the extra you did not use.
