# Cartesian to Cylindrical Coordinates Conversion Calculator

### Cartesian (Rectangular) to Cylindrical Coordinates System Diagram

This cylindrical coordinates conversion calculator converts the rectangular (or cartesian) coordinates of a unit to its equivalent value in cylindrical coordinates, according to the formulas shown above.

Rectangular coordinates are depicted by 3 values, (X, Y, Z). When converted into cylindrical coordinates, the new values will be depicted as (r, θ, z).

To use this calculator, a user just enters in the **(X, Y, Z)** values of the rectangular coordinates and then clicks the 'Calculate' button,
and the cylindrical
coordinates will be automatically computed and shown below.

This calculator can be used to convert 2-dimensional (2D) or 3-dimensional cartesian coordinates to its equivalent cylindrical coordinates. If desired to convert a 2D cartesian coordinate, then the user just enters values into the X and Y form fields and leaves the 3rd field, the Z field, blank. Z will will then have a value of 0. If desired to convert a 3D cartesian coordinate, then the user enters values into all 3 form fields, X, Y, and Z.

By default, the calculator will compute the result in degrees. However, by using the drop-down menu, the option can changed to radians, so that the
result can also be computed in radians.

**Example Calculations**

Convert the rectangular coordinates (3, 4, 5) into its equivalent spherical coordinates.

This answer is calculated in degrees. In radians, the value of θ would be 0.93.
