Convert a volume of material into weight in tons and tonnes using common material densities.
Different materials weigh very different amounts for the same volume. A cubic metre of dry gravel weighs around 1.5 tonnes, while a cubic metre of MOT Type 1 sub-base is closer to 2 tonnes. Always order by weight when your supplier sells by the tonne.
About 1.15 tonnes, since a cubic yard is 0.765 cubic metres and gravel weighs roughly 1.5 tonnes per cubic metre.
No. A metric tonne is 1000 kg, while a US (short) ton is about 907 kg. We show both so you can match your supplier.
They are typical averages. Moisture content and how compacted the material is will change the real weight, so treat the result as a close estimate.
Because a cubic yard of light mulch weighs far less than a cubic yard of gravel. Density tells you how heavy each material is for its volume.
About 1.2–1.4 tonnes, depending on gravel type and moisture. The calculator applies a realistic density for each material you choose.
Calculate the volume and weight of gravel needed for driveways, paths, and landscaping.
OpenCalculate the tonnage and volume of any aggregate – gravel, sand, ballast, MOT or crushed stone.
