Square Feet To Cubic Yard Calculator:  Square feet and cubic yards

Square feet or ft2 is a unit of area, whereas, cubic yards or yd3 is a unit of volume.

Often we need to calculate the volume for construction or landscape material, for example, soil, mulch, etc., and we use cubic yards to express this volume. For example, if you are preparing a flower bed and want to know how much mulch and soil you need.

Let us consider the given figure to understand the difference and relation between square feet and cubic yards. The figure shows a rectangular plot area that is 9 feet long and 6 feet wide. We can calculate the area of this rectangular plot as:

Square feet to cubic yards calculation.
𝐴𝑟𝑒𝑎=𝑙𝑒𝑛𝑔𝑡ℎ×𝑤𝑖𝑑𝑡ℎ=9 ft×6 ft=54 ft2

If we dig up the whole plot to 6-inch (or 0.5 ft) depth, the volume of the resulting bed would be:

𝑉𝑜𝑙𝑢𝑚𝑒=𝐴𝑟𝑒𝑎×𝑑𝑒𝑝𝑡ℎ=54 ft2×0.5 ft=27 ft3

Using the relation 1 yd=3 ft or 1 yd3=27 ft3, we can write the above equation as:

𝑉𝑜𝑙𝑢𝑚𝑒=27 ft3=1 yd3


How to convert square feet to cubic yards

Since square feet is a measure of area, and cubic yards is a measure of volume, to convert square feet to cubic yards, we need to follow the given steps:

  1. Determine the area by using the appropriate formula and converting the unit of area to square feet.
  2. Measure the depth/height of the area and convert it to feet as well.
  3. Multiply the area and depth/height, and you will get volume in cubic feet.
  4. Divide the volume in cubic feet by 27 to get the volume in cubic yards.
  5. You can also use our square feet to cubic yards calculator for this purpose!
