A cubic yard is 27 cubic feet — a 3 ft cube. No waste is added here; add it on the material calculator you are ordering from.

Show the math
  • Area 10 ft × 10 ft = 100 sq ft
  • Volume 100 sq ft × 0.5 ft = 50 ft³
  • To cubic yards 50 ÷ 27 = 1.85 yd³
  • Weight 50 × 110 lb/ft³ = 2.75 tons

Frequently asked questions

How many cubic feet are in a cubic yard?

27. A cubic yard is a cube three feet on each side, so 3 × 3 × 3 = 27 cubic feet.

How do I calculate cubic yards from square feet?

Multiply the square footage by the depth in feet, then divide by 27. For a depth in inches, divide the inches by 12 first.

How many cubic yards in a cubic metre?

One cubic metre is 1.308 cubic yards, and one cubic yard is 0.7646 cubic metres.

How much does a cubic yard weigh?

It depends on the material: about 2,970 lb for ¼–2 in gravel, 2,200 lb for dry topsoil, 4,050 lb for concrete and around 600 lb for bark mulch.

How many cubic yards do I need?

Multiply area in square feet by depth in feet, then divide by 27. A 10 × 10 ft area at 6 inches deep is 50 cubic feet, which is 1.85 cubic yards. Depth in inches divided by 12 gives the depth in feet.

Yards, tons and truckloads

Suppliers quote aggregate and soil by the ton, so convert with the material weight: ¼–2 in gravel is about 1.5 tons per cubic yard, dry topsoil about 1.1 tons, concrete just over 2 tons and bark mulch about 0.3 tons. A standard dump truck carries 10–14 cubic yards.

What this calculator assumes
  • A cubic yard is 27 cubic feet, and a cubic metre is 35.3147 cubic feet.
  • Weights use loose, as-delivered densities, listed on the how we calculate page.
  • No waste allowance is added — this is a straight volume conversion.
