How this calculator works
Cylinder volume = π × radius² × height. Filled volume = volume × fill percentage ÷ 100. Use consistent length units.
Variables and inputs
- Radius
- Required numeric input. finite numeric value; calculator-specific validation applies.
- Height
- Optional numeric input. finite numeric value; calculator-specific validation applies.
- Fill level
- Optional numeric input. finite numeric value; calculator-specific validation applies.
- Quantity
- Optional numeric input. finite numeric value; calculator-specific validation applies.
- Price, optional
- Optional numeric input. finite numeric value; calculator-specific validation applies.
How to interpret the result
The calculator returns full cylinder volume, volume in litres, filled volume from percentage, combined volume for multiple cylinders, estimated material cost. Read each output against the assumptions you entered, compare alternatives one variable at a time, and use the result as an estimate rather than a promise.
Common mistakes to avoid
- Mixing units or entering a rate as a decimal when the field requests a percentage.
- Rounding intermediate values instead of the final displayed result.
- Leaving out a cost, timing rule or local requirement listed in the assumptions below.
Practical uses
Use the cylinder volume calculator to check a real scenario, compare a changed assumption and explain the arithmetic before relying on a quote, specification or decision.
Worked example
A cylinder with a 2 m radius and 5 m height has a volume of about 62.832 m³, or 62,832 litres. At 75% fill it contains about 47.124 m³ before allowances.
Assumptions and limitations
- the object is a right circular cylinder with a constant internal radius
- all entered dimensions use the selected common length unit and exclude wall thickness
- results are estimates; confirm rates, prices, units and professional requirements that apply
Important notes
Results are estimates based on the values entered. Confirm rates, prices, units and professional requirements that apply in your location. Review the Answer Atlas Calculation Standard and corrections policy for formula, privacy and correction rules.
Frequently asked questions
Should I enter radius or diameter?
Enter radius, which is half the diameter. If you measured the full width across the circle, divide it by two first.
Can this calculate tank capacity?
Yes, if the tank is a right circular cylinder and the dimensions use metres. For partial-fill estimates, set the fill percentage.
Does this include wall thickness or unusable space?
No. It is a geometric estimate. Wall thickness, fittings, slope, internal obstructions and safety margins should be checked separately.
