Quick Reference
The cylinder calculator finds the volume and surface area of any right circular cylinder in seconds. Enter the radius and height in your preferred unit — millimetres, centimetres, metres, inches, or feet — and instantly get volume, total surface area, lateral surface area, base area, diameter, and circumference. Perfect for engineering, packaging, construction, and classroom geometry problems.
Volume = π × r² × h, where r is the radius of the circular base and h is the height. For example, a cylinder with radius 5 cm and height 10 cm has a volume of π × 25 × 10 ≈ 785.40 cm³.
Lateral surface area (2πrh) covers only the curved side wall. Total surface area adds both circular end caps (each πr²), giving 2πr(r + h). Use total surface area when calculating paint or material needed to enclose the cylinder completely.
Yes. Select your unit from the dropdown — mm, cm, m, in, or ft — and all results are shown in that unit. Volume is given in cubic units (e.g. in³) and areas in square units (e.g. in²).
The radius (r) is the distance from the centre of the circular base to its edge. The diameter is twice the radius (2r) and spans the full width of the circle. If you only know the diameter, halve it to get the radius before calculating.
