Calculate cubic yards (and cubic metres) of material needed from length, width and depth — ideal for concrete, soil and aggregate.
Enter the length and width of the area, then the depth (inches for imperial, centimetres for metric), and set how many identical areas you have. The tool returns the volume in cubic yards and cubic metres — the units bulk materials are sold in. Concrete, soil (“topsoil”), gravel (“aggregate”) and mulch (“bark”) are all ordered this way.
| From | To |
|---|---|
| 1 cubic yard | 27 cubic feet |
| 1 cubic yard | 0.765 cubic metres |
| 1 cubic metre | 1.31 cubic yards |
A bed 12 ft × 9 ft filled 3 in deep = 12 × 9 × 0.25 = 27 ft³ = exactly 1 cubic yard. The same bed in metric (3.66 m × 2.74 m × 76 mm) ≈ 0.76 m³.
Tip: order 5–10% extra for materials that settle or compact, such as soil, mulch and crushed stone.
Multiply length × width × depth (all in feet) to get cubic feet, then divide by 27. This calculator does it for you and also converts depth from inches.
There are 27 cubic feet in one cubic yard (3 ft × 3 ft × 3 ft).
A cubic yard of concrete covers 81 square feet at 4 inches deep, or 108 square feet at 3 inches deep.
One cubic metre is about 1.31 cubic yards, and one cubic yard is about 0.765 cubic metres. The calculator converts between the two automatically.
Multiply the cubic yards by the material density. Our Cubic Yards to Tons calculator does this for common materials like gravel, soil and concrete.
