How to Convert Square Feet to Cubic Yards for Concrete

Construction is a very precise activity. The amount of a particular material needed for a project needs to be known to the inch and should never be ballpark estimated. Concrete is one of the most commonly used construction materials due to its durability, ease of use and cost-effectiveness. Concrete measurements frequently need to be converted to determine how much is needed to lay down a foundation or complete another activity. Converting square feet to cubic yards for the purpose of concrete pouring can be done with some simple mathematical calculations.

A calculator is useful when making conversions for concrete measurement.

Step 1

Calculate the square feet of the space by measuring the length with a tape measure and multiplying it by the width.

Step 2

Determine the depth or height that you need for the concrete by using the tape measure to mark the vertical space taken up by the concrete. Multiply that number by the square footage to determine cubic feet.

Step 3

Divide your cubic foot number by 27, since there are 27 cubic feet in one cubic yard. The resulting number will be the cubic yards needed for the concrete.
