Find how many cubic yards of concrete, soil, mulch or gravel a space needs. Enter length, width and depth, add an allowance for waste, and order with confidence. Free, private, and runs entirely in your browser.
Multiply length, width and depth after converting each to feet, then divide the cubic feet by 27 to get cubic yards. A percentage for waste and settling is then added on top.
How many cubic feet are in a cubic yard? 27, since 3 ft × 3 ft × 3 ft = 27 ft³.
How much extra should I order? Many projects add 5% to 10% for waste, spillage and uneven ground. Use more for rough or sloped areas.
A patio base is 12 ft long, 10 ft wide and 0.5 ft (6 in) deep. Volume = 12 × 10 × 0.5 = 60 ft³, and 60 ÷ 27 ≈ 2.22 yd³. Adding 10% gives 2.22 × 1.10 ≈ 2.44 yd³, which is about 1.70 m³ before the allowance.
How many cubic yards in a truck load? Small dump trucks carry roughly 5 to 10 cubic yards, but check the supplier since capacities and weight limits vary.
How much concrete is a 10 by 10 slab? At 4 inches thick it is about 1.23 cubic yards. Our concrete calculator also estimates bags.
The cubic yard is the cube of the yard, which is 3 feet, so it holds exactly 27 cubic feet or about 0.7646 cubic meters. In the United States, bulk materials such as concrete, topsoil, mulch and gravel are still sold by the cubic yard, while many other countries use cubic meters.
Use this calculator before ordering ready-mix concrete, a landscaping delivery or a dumpster. Enter the area and depth, keep the waste allowance, and round up to the supplier minimum. Weight depends on the material, so ask the supplier for the density when trucking limits matter.
How do I convert cubic yards to tons? Multiply by the material density. For example, gravel is often about 1.3 to 1.5 tons per cubic yard, but it varies.
How do I convert cubic yards to cubic feet? Multiply by 27. Two and a quarter cubic yards is 60.75 cubic feet.
