Cubic yard formula

Cubic yards = length (ft) × width (ft) × depth (ft) ÷ 27

LengthWidthDepth
Measure length and width in feet and depth in inches. The calculator converts everything to cubic yards.

A cubic yard is 3 ft × 3 ft × 3 ft, which is 27 cubic feet. Convert depth from inches by dividing by 12 first. A 10 × 10 ft area 4 inches deep is 33.3 cubic feet, or 1.23 cubic yards.

Odd shapes. Split the area into rectangles and add them. For a circle, use 3.14 × radius² as the area, then multiply by depth.

For tons by product, use the gravel, topsoil or sand calculators.

How many cubic feet are in a yard?

There are 27 cubic feet in one cubic yard, because a cubic yard measures 3 ft × 3 ft × 3 ft. Divide cubic feet by 27 to get cubic yards, or multiply cubic yards by 27 to get cubic feet. For example, 100 cubic feet is 3.7 cubic yards.
