How to convert square feet to cubic yards

To convert square feet to cubic yards, you simply multiply your square footage figure by the height or depth of the area (in feet) to get a volume measurement in cubic feet. You then divide the total by 27 to get your measurement in cubic yards.

Should your height or depth figure be in inches, simply divide it by 12 to get your feet figure (there are 12 inches in a foot). Also, note that there are 27 cubic feet in a cubic yard.

Diagram of how to convert square feet to cubic yards

Formula for cubic yards

Cubic yards = [width × length × height in ft] ÷ 27

Square feet to cubic yards

Cubic yards = [square feet × height in ft] ÷ 27

How to calculate cubic yards

  1. Calculate your square feet area: Width × length
  2. Calculate the volume: Multiply your area figure by the depth/height. This gives you a volume figure in cubic feet
  3. Convert to cubic yards: Divide your cubic feet figure by 27. You now have your answer.

How do I convert cubic yards to square feet?

In order to carry out this calculation, we need to include an extra dimension (height/depth, for example). Once you have this extra measurement, you can incorporate it into the calculations below.

Note: these formulae assume all measurements are in feet:

Formula for square feet

Square feet = width (ft) × length (ft)

Cubic yards to square feet

Square feet = (cubic yards × 27) ÷ height (ft)

Of course, if you use our calculator at the top of the page, it'll work these calculations out for you. Note that you can convert square feet to cubic feet here.
