How do I convert square feet to cubic yards?
Let's start off by discussing the use of the word 'convert'. Due to the fact that the square foot is a unit of area, with two dimensions, and the cubic yard is a unit of volume, with three dimensions, this isn't a conversion - it's a calculation. To calculate cubic yards from a square feet figure, we need to include an extra dimension - height/depth.
It's important that the height/depth dimension is in the same unit as the others. In this case, it should be a measurement in feet. We have an additional calculator, should you wish to calculate cubic feet from square feet.
Note: these formulae assume all measurements are in feet. We divide by 27 because there are 27 cubic feet in a cubic yard.
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
- Calculate your square feet area: Width × length
- Calculate the volume: Multiply your area figure by the depth/height. This gives you a volume figure in cubic feet
- 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?
As mentioned above, this is a calculation and not a conversion because a cubic yard is a unit of volume (with three dimensions) and a square foot is a unit of area (with two dimensions). 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.
