What is the Volume Of A Cylinder Calculator?
A 12-ounce soda can is a cylinder 2.6 inches across and 4.8 inches tall — and π × 1.3² × 4.8 ≈ 25.5 cubic inches of interior, which is 14 fluid ounces of space for 12 ounces of soda plus the headroom the fizz needs. The volume of any cylinder is the base circle's area times its height (V = πr²h): square the radius, multiply by π, multiply by height. Coffee mugs, paint cans, and candle jars all surrender their capacity to the same three moves.
Type the Radius and Height into their boxes and read the Volume output — enter 1.3 and 4.8 for the soda can and get about 25.5 cubic inches. Divide by 1.8047 for fluid ounces if you are sizing a drink container, or by 231 for gallons on bigger tanks. A homebrewer checking whether a 6-inch-radius, 24-inch-tall fermenter holds a 5-gallon batch enters 6 and 24, reads about 2,714 cubic inches, and divides by 231 to confirm 11.7 gallons of headroom-friendly capacity.
With the pre-filled defaults — Radius 3, Height 10 — the Volume Of A Cylinder Calculator returns Volume 282.7433. Change any input and those results update instantly, so you can see exactly how each number you enter moves the answer.
How to Use the Volume Of A Cylinder Calculator
- 1Halve the diameter to get the radius and type it in the Radius box — for example, 1.3 for a soda can.
- 2Type the height in the Height box — for example, 4.8.
- 3Read the Volume output: about 25.5 cubic inches for the can.
- 4Convert to fluid ounces by dividing by 1.8047, or to gallons by dividing by 231.
- 5For a quick sanity check, compare against a known container — a gallon jug is 231 cubic inches.
- 6Measure the inside dimensions when capacity matters; wall thickness eats a surprising amount of volume.

Calculation Progression Roadmap
How the Volume Of A Cylinder Calculator turns your inputs into a result, step by step — from the values you type to the answer you read.
Gather your inputs
Type in your Radius and Height. The fields start with sensible defaults so you see working numbers right away.
Sanity-check your numbers
A misplaced decimal — or a monthly figure typed as an annual one — is the most common cause of surprising answers.
The math runs itself
The calculator evaluates π × Radius^2 × Height on every keystroke — there is no submit button to press.
Read your results
Your Volume appears instantly. With the pre-filled defaults, that is Volume 282.7433. Change any input to see the effect immediately.
Test a what-if
Try a bigger and a smaller value for one input. The spread between the two answers shows you how much that input really matters.
Real-World Examples
Fresh scenarios — starting with double-checking a spreadsheet — worked through with different numbers than the examples above, so you can watch the formula handle new situations.
Double-checking a spreadsheet
