27 cubic feet makes a cubic yard

A cubic yard is 3 ft on every side -- 3x3x3 -- which is exactly 27 cubic feet. Most bulk material calculators and suppliers quote cubic yards, while a lot of material math (length x width x depth) naturally comes out in cubic feet first.

A cubic yard is a cube 3 ft on each side, so its volume is 3 x 3 x 3 = 27 cubic feet. To go from cubic feet to cubic yards, divide by 27; to go the other way, multiply by 27.

This conversion comes up constantly in construction: concrete, gravel, mulch, topsoil and sand are all typically priced and delivered by the cubic yard, but the raw volume math from a project's dimensions (length x width x depth, all in feet) naturally produces cubic feet first.

For the material-specific version of this conversion -- turning cubic yards into tons for gravel, sand, mulch or concrete -- see the Cubic Yards to Tons Converter, which accounts for each material's typical density.

Where these numbers come from

Standard unit-conversion factors. Material weight figures (where used) are typical averages -- check your specific supplier for exact density.

Frequently asked questions

Why do suppliers sell by the cubic yard instead of cubic feet?

A cubic yard is a more practical unit for the quantities involved in most residential and commercial projects -- it's the size of a small pickup truck load, roughly, which makes it an intuitive unit for both buyers and delivery trucks.

Does this work for any material?

Yes, this is a pure volume conversion (27 cubic feet per cubic yard) that applies to any material -- concrete, gravel, mulch, soil, sand, or anything else measured by volume.

How do I get cubic feet from my project's dimensions?

Multiply length x width x depth, all measured in feet (convert inches to feet first by dividing by 12). That gives cubic feet directly; divide by 27 for cubic yards.
