Cylindrical Coordinates Calculator

Convert between 3D Cartesian (x, y, z) and cylindrical (r, theta, z) coordinates - useful for problems with rotational symmetry around the z-axis.

Frequently Asked Questions

What are cylindrical coordinates?

A 3D system (r, theta, z) that combines polar coordinates in the xy-plane with an unchanged z-axis. Natural for problems with rotational symmetry around z.

How is cylindrical different from spherical?

Cylindrical keeps the z-axis distance directly. Spherical replaces z with a polar angle phi measured from the z-axis. Both share an azimuth theta in the xy-plane.

When do I integrate in cylindrical?

When the region or integrand has rotational symmetry around an axis. Pipes, rotational solids, antenna patterns, and Maxwell-equation problems near coaxial cables benefit.
