Enter your area in square yards and the depth to convert to cubic yards — the number you need when ordering bulk materials like mulch, gravel, soil, or concrete.
The Square Yard to Cubic Yard Calculator is used to quickly calculate key measurements and estimates so you can plan materials, costs, and project scope with confidence.
yd³ = yd² × (depth in inches ÷ 36). The ÷ 36 converts inches to yards (36 inches = 1 yard).
50 × (4 ÷ 36) = 50 × 0.1111 = 5.56 cubic yards = 150 cubic feet. That's about 4 tons of gravel or 3 tons of mulch.
200 × (6 ÷ 36) = 200 × 0.1667 = 33.33 cubic yards = 900 cubic feet. That's a large delivery — about 2-3 dump truck loads.
1 cubic yard covers 36 yd² at 1 inch deep, 12 yd² at 3 inches, 9 yd² at 4 inches, or 3 yd² at 1 foot deep.
| Area (yd²) | 2" deep | 4" deep | 6" deep | 12" deep |

yd³ = yd² × (depth in inches ÷ 36). Depth must be in yards or converted.
No — square yards is area (2D) and cubic yards is volume (3D). Depth is required.
At 1": 36 yd². At 3": 12 yd². At 4": 9 yd². At 6": 6 yd². At 12": 3 yd².
100 × 3/36 = 8.33 yd³.
