Cubic Yards Calculator
Box mode multiplies length, width, and depth in one unit, then reports yd³, ft³, and m³. Convert mode scales a typed volume among yd³, ft³, m³, and in³. Estimate only, not a permit, code check, or engineered design.

How to get cubic yards
- Choose box volume or convert volume.
- For a box, enter length, width, depth, and one shared dimension unit.
- For convert, enter a volume and choose yd³, ft³, m³, or in³.
- Read cubic yards plus the other volume units shown. Estimate only.
Cubic yard volume
Box product or unit conversion
| Box ft³ | length × width × depth (converted to feet) |
|---|---|
| Yards from box | ft³ / 27 |
| Convert yd³ | value × factor for from unit |
| ft³ factor | 1 yd³ = 27 ft³ |
| in³ factor | 1 yd³ = 46656 in³ |

What this cubic yards page covers
Box mode sizes a rectangular solid. Convert mode only changes volume units. Concrete bags and slab depth sit on concrete. Cut volume sits on excavation. Tiny solids sit on cubic inches.
How cubic yards are computed
Box: convert each side to feet, multiply for ft³, divide by 27 for yd³. Convert: scale value into yd³ using yd3=1, ft3=1/27, m3≈1/0.76455, in3=1/46656, then list the other units.
Use cases
A 10 by 10 by 0.5 ft pad in yards. Converting 2 yd³ into cubic feet before ordering bags. Not a cut-and-fill design.
Limits
No irregular shapes and no swell percent in convert mode. Estimate only, not a permit, code check, or engineered design. Nothing is uploaded.
