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 a tool used to quickly calculate measurements, conversions, and estimates so you can plan materials and project decisions 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.
