Math

Cartesian to Cylindrical Coordinates: calculate results from explicit inputs, with a formula and worked example.

Formula

r = √(x²+y²); θ = atan2(y,x); z unchanged

Example Calculation

Example inputs
  • x: 3
  • y: 4
  • z: 2

Point (3,4,2) gives r=5, θ≈53.1301°, z=2.

Frequently asked questions

How do I use this calculator?

Enter x, y, z. The result updates automatically. Use Reset to restore the example values.

What method does it use?

r = √(x²+y²); θ = atan2(y,x); z unchanged. Euclidean geometry. Use one consistent length unit; areas and volumes use its square and cube. Degenerate shapes are rejected. Very thin shapes may lose floating-point precision. Angle convention is −180° to 180°, measured from positive x.

Why might a rounded result differ?

The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.

Are my inputs saved online?

No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
