Calculate volume in cubic yards (yd³) from width × length × depth in yards. 1 yd³ = 27 ft³ ≈ 0.765 m³ — the standard unit for ordering concrete in the US.

How to calculate cubic yards
yd³ = width(yd) × length(yd) × depth(yd). Convert feet first (ft ÷ 3) or inches (in ÷ 36).
Common mistake
Leaving dimensions in feet. A 9 × 12 ft area with 6 in (0.5 ft) depth is 9×12×0.5 = 54 ft³ = 2 yd³ — not 9×12×6 = 648.
