Cubic Yard Calculator

Multiply length × width × depth (in feet) to get cubic feet, then divide by 27. If your depth is in inches, divide that depth by 12 first to convert it to feet.

It depends on the material. Approximate weights per cubic yard: concrete ≈ 4,050 lb (2 tons), gravel ≈ 2,700 lb (1.35 tons), topsoil ≈ 2,200 lb (1.1 tons), mulch ≈ 800 lb (0.4 tons). The calculator multiplies by the right density when you pick a material.

Add 5–10% to cover settling, compaction, spillage, and over-pour at edges. For very small jobs, round up further to whole bags or to whatever the supplier delivers in.

Suppliers sell both ways. Truck deliveries are usually quoted in tons; bagged or scooped quantities in cubic yards. Use whichever the supplier asks for — the calculator gives you both.
