# Cartesian to Spherical Coordinates Calculator

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

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

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

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 spherical
coordinates will be automatically computed and shown below.

This calculator can be used to convert 2-dimensional (2D) or 3-dimensional rectangular coordinates to its equivalent spherical coordinates. If desired to convert a 2D rectangular coordinate, then the user just enters values into the X and Y form fields and leaves the 3rd field, the Z field, blank. If desired to convert a 3D rectangular 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 will be computed in radians.

**Example Calculations**

### Example With Rectangular (Cartesian) Coordinates
