Gravel to order: 0.65 yd³ · 0.83 US short tons · 0.50 m³ · 0.75 tChoose area or length × width, then enter the layer depth. The result shows cubic metres and yards plus metric tonnes and US short tons. Pick a loose-stone preset or enter your supplier's density; the optional extra percentage is added only after the base volume is calculated.

Area and depth are things you measure; the density is not. Loose stone runs from about 1.4 to 1.7 t/m³, and the same 0.5 m³ weighs 0.7 t at the bottom of that band and 0.85 t at the top. Use the figure your supplier quotes when you have one.
Suppliers price loose stone by the tonne, but what fills the area is a volume. Area × depth gives that volume, and the density is the only bridge between the two.
The 1.5 t/m³ custom default is only a general estimate. Wet or compacted material can have a different bulk density, so use your supplier's figure before ordering. The separate allowance increases order quantity without changing the chosen density.
OutdoorBrite lists loose pea gravel at 1.538, crushed stone at 1.602 and river rock at 1.570 t/m³. The older 1.5 custom default remains an editable general estimate for existing links. Supplier density takes priority for an order.
MisconceptionThe area needs 0.5 m³, so I ordered 0.5 tonnes.
CorrectionThose are different units, and only the density connects them. At 1.5 t/m³ that 0.5 m³ is 0.75 tonnes, half as much again as you ordered.
MisconceptionI entered the layer depth in metres.
CorrectionThe unit is shown beside the depth field. In metric mode enter 5 for a 5 cm layer; in US mode enter the depth in inches.
MisconceptionThe density is fixed at 1.5, so I left the field alone.
CorrectionThe presets use different published loose-material densities. Select custom to enter a supplier value; the 1.5 t/m³ default is an estimate, not a fixed property of gravel.
| Dimensions / area | Base volume | Weight, 0% extra |
|---|---|---|
| 10 m² × 5 cm, 1.5 t/m³ | 0.50 m³ / 0.65 yd³ | 0.75 t / 0.83 US ton |
| 12 ft × 10 ft × 3 in, 1.68 t/m³ | 0.85 m³ / 1.11 yd³ | 1.43 t / 1.57 US tons |
| 5 m × 1 m × 15 cm, 1.68 t/m³ | 0.75 m³ / 0.98 yd³ | 1.26 t / 1.39 US tons |
Multiply the area by the depth of the layer, then by the density. For 10 m² at 5 cm deep the volume is 0.5 m³, and at a typical 1.5 t/m³ that is 0.75 tonnes.
The required depth depends on the stone, subgrade, load and project design. Enter the planned layer depth; ask your supplier or designer for a suitable depth before ordering a driveway.
Choose a loose-material preset or select custom and enter your supplier's bulk density in t/m³. The 1.5 custom default is only an estimate; wet or compacted material may be heavier.
Yes. The live result gives both m³ and cubic yards beside metric tonnes and US short tons. Tell the supplier which volume or weight unit you mean.
Set the extra percentage yourself. Zero shows the measured base volume; a nonzero value increases the order volume and weight, and the result also names the unchanged base volume. This allowance is a planning choice, not a measured material property.
