Volume Measurement
A cylinder cubic yardage calculator determines the volume of a cylindrical form in cubic yards. It is useful for ordering ready-mix concrete, calculating fill for round columns or piers, and estimating material for cylindrical tanks and pipes.
First calculate the cylinder volume in cubic feet using pi times the radius squared times the height. Then divide by 27 to convert to cubic yards.
The calculator also shows cubic feet, gallons, and litres for comparison, and can estimate weight in tons using material density if applicable.
Cubic yards = (pi x (Diameter / 2)^2 x Height) / 27
Calculate cylinder volume in cubic feet, then divide by 27 to get cubic yards.
Ready-mix concrete is sold by the cubic yard. For round columns, piers, or footings, this calculator gives you the ordering quantity directly. Add a waste allowance for spillage and overfill.
Frequently asked questions
Measure the diameter and depth of the footing, enter them into the calculator, and the result gives you the cubic yards of concrete to order.
Yes. Adding 5 to 10 percent to the calculated volume accounts for spillage, overfill, and forming irregularities.
