One cubic metre of crusher dust weighs about 1.8 tonnes and covers about 20 square metres at 50mm.
How to work out how much crusher dust you need
- Measure the area in metres and multiply length by width.
- Pick a depth in mm and multiply it by the area to get a volume.
- Multiply the volume by the bulk density, 1800 kg per cubic metre for crusher dust, to get a weight.
- Divide the weight by your supplier's tonne or bulk bag 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.
How many tons in a cubic yard of crusher dust?
About 1.52 US tons, at 1800 kg per cubic metre. Because published densities run from 1500 to 2100, the honest answer is a range: between 1.26 and 1.77 tons per cubic yard depending on grading and how wet the load is.
How many cubic yards in a ton of crusher dust?
About 0.66 cubic yards. One tonne is about 0.56 cubic metres.
How much does crusher dust weigh?
Between 1500 and 2100 kg per cubic metre, a spread of 40 percent. Loose to compacted. Crusher dust binds hard under a plate compactor. The calculator above uses 1800, and you can replace it with your own supplier's figure.

Crusher dust and stone dust
In the US trade the same material is sold as stone dust, ordered in cubic yards and tons, so the stone dust calculator works in those units and at those depths.
