This online calculator will calculate the various properties of a cylinder given 2 known values. This is a right circular cylinder where the top and bottom surfaces are parallel but it is commonly referred to as a "cylinder".
* Units: Note that units are shown for convenience but do not affect the calculations. The units are in place to give an indication of the order of the results such as ft, ft2 or ft3. For example, if you are starting with mm and you know r and h in mm, your calculations will result with V in mm3, L in mm2, T in mm2, B in mm2 and A in mm2.
Below are the standard formulas for a cylinder. Calculations are based on algebraic manipulation of these standard formulas.
** The area calculated is only the lateral surface of the outer cylinder wall. To calculate the total surface area you will need to also calculate the area of the top and bottom. You can do this using the circle calculator.
Use the following additional formulas along with the formulas above.
