Cubic Yard

Definition

A cubic yard is 27 cubic feet — the US bulk unit for concrete, gravel, soil and mulch. Volume = length × width × (depth in inches / 12), then yards = cubic feet / 27. One cubic metre is about 1.308 cubic yards. Ready-mix is usually cheaper than bags above about 1 yd³ (0.76 m³). US 60 lb bags yield about 0.45 ft³ and 80 lb bags about 0.60 ft³; metric mode still uses those bag yields as a planning number.
