Elliptical Cylinder Calculator
Calculate right elliptical cylinder volume and base areas from two semi-axis lengths and perpendicular height privately in your browser.
Find the volume of a cylinder with an elliptical base.
A right elliptical cylinder has two matching parallel elliptical bases and a perpendicular height h. Enter perpendicular semi-axes a and b, each half a full base width. One base area B = πab; volume V = πabh; combined base area = 2πab. For a = 3, b = 2 and h = 5, one base area is 6π ≈ 18.8495559215 square units and volume is 30π ≈ 94.2477796077 cubic units. Equal semi-axes give an ordinary circular cylinder. Either semi-axis may be the larger one. The combined base area excludes the curved side and is not total surface area. These formulas assume a constant elliptical cross-section and a right cylinder. Use the same length unit for all inputs, from 1e-50 to 1e50; scientific notation is accepted. Results use browser floating-point arithmetic rounded to 12 significant digits. All calculations stay in your browser.
Frequently Asked Questions
Everything you need to know about this tool, how it works, and privacy.
How do I calculate elliptical cylinder volume?
Multiply π by the two base semi-axes and perpendicular height: V = πabh. Semi-axes 3 and 2 with height 5 give 30π, approximately 94.2477796077 cubic units.
Should I enter full widths or semi-axes?
Enter semi-axes, which are half the full widths of the elliptical base along its two perpendicular axes. Divide each full width by two first.
Does the base area include the curved side?
No. One base area is πab and both bases together have area 2πab. Neither includes the curved lateral surface; this calculator does not report total surface area.
Can the two semi-axes be equal?
Yes. Equal semi-axes give a circular cylinder and the formula becomes V = πr²h. Use positive lengths from 1e-50 to 1e50 in consistent units. Scientific notation is accepted, and inputs stay in your browser.
