Concrete Cylinder Calculator

What is Concrete Cylinder Calculator?

Calculate the volume of cylindrical concrete forms, test specimens and round elements.

How to use the calculator

1. Enter the project dimensions and quantities.
2. Choose the correct unit for each measurement.
3. Review the calculated result and waste allowance.
4. Check the estimate against project specifications.

Formula and calculation method

V = π × Diameter² × Height ÷ 4 × Quantity.

Worked example

Enter representative project measurements, apply the formula shown above, and compare the calculated quantity with the purchase quantity after waste is added.

Measurement and unit explanation

Use one unit per input and confirm whether the output is cubic meters, cubic feet, cubic yards, liters, kilograms, pounds, tonnes, square meters, or block count as applicable.

Accuracy and assumptions

For laboratory specimens, follow the applicable testing standard. This tool determines geometric volume only. Results are estimates and should be checked against actual site dimensions, material specifications, waste, joints, openings, moisture, and professional requirements.
