Square Feet to Cubic Yards
Square feet to cubic yards needs a depth. At 4 inches deep, 1 ft² = 0.0123 yd³. At 6 inches, 1 ft² = 0.0185 yd³. Multiply your square footage by the table value to get cubic yards.
The formula
yd³ = ft² × (depth in inches ÷ 12) ÷ 27
| Depth | 1 Square = |
|---|---|
| 1 in | 0.00309 yd³ |
| 2 in | 0.00617 yd³ |
| 3 in | 0.00926 yd³ |
| 4 in | 0.01235 yd³ |
| 5 in | 0.01543 yd³ |
| 6 in | 0.01852 yd³ |
| 8 in | 0.02469 yd³ |
| 12 in | 0.03704 yd³ |
