How to Calculate Concrete Yardage

Using measurements in feet:

Volume in Cubic Feet (ft³) = Width x Length x Depth

Volume in Cubic Yards (yd³) = Volume in Cubic Feet (ft³) / 27

Volume in Cubic Meters (m³) = Volume in Cubic Feet (ft³) x 0.0283

Using measurements in feet:

Area of the Circle (ft²) = π x (Diameter / 2)²

Volume in Cubic Feet (ft³) = Depth x Area

Volume in Cubic Yards (yd³) = Volume in Cubic Feet (ft³) / 27

Volume in Cubic Meters (m³) = Volume in Cubic Feet (ft³) x 0.0283

π = 3.14

Using measurements in feet:

Volume in Cubic Feet (ft³) = Thickness x Length x Height

Volume in Cubic Yards (yd³) = Volume in Cubic Feet (ft³) / 27

Volume in Cubic Meters (m³) = Volume in Cubic Feet (ft³) x 0.0283

Using measurements in feet:

Volume in Cubic Feet (ft³) = Width x Length x Height

Volume in Cubic Yards (yd³) = Volume in Cubic Feet (ft³) / 27

Volume in Cubic Meters (m³) = Volume in Cubic Feet (ft³) x 0.0283

Using measurements in feet:

Volume in Cubic Feet (ft³) = Height x Area

Volume in Cubic Yards (yd³) = Volume in Cubic Feet (ft³) / 27

Volume in Cubic Meters (m³) = Volume in Cubic Feet (ft³) x 0.0283

π = 3.14

Using measurements in feet:

We calculate the volume in sections from the ground to the top of each section. The Curb and Gutter are each a section.

Volume in Cubic Feet Under Curb = Curb Depth x (Curb Height + Flag Thickness) x Length

Volume in Cubic Feet Under Gutter = Gutter Width x Flag Thickness x Length

Volume in Cubic Feet = Volume in Cubic Feet Under Curb + Volume in Cubic Feet Under Gutter

Volume in Cubic Yards (yd³) = Volume in Cubic Feet (ft³) / 27

Volume in Cubic Meters (m³) = Volume in Cubic Feet (ft³) x 0.0283
