With this calculator you can convert cartesian coordinates of a point into polar coordinates and vice versa. The cartesian coordinates of a point are the value of the abscissa x an the ordinate y. The polar coordinates are the radius r for the distance between the point and the pole (the origin of the cartesian coordinate system) and the angle Θ (or azimut) for the angle (anti-clockwise) between the axis with the angle 0° (corresponding to the abscissa in the cartesian coordinate system) and the point.

Type the cartesian coordinates or the polar coordinates of a point into the
corresponding fields. After a click with the mouse on any free space of the window
or the "calculate"-button the calculation is performed.
The fields with input data get a light-green background, fields with calculated
values are coloured pink. The calculation is performed with the pair of coordinates
Move the mouse over a unit or click on it to read its full name. Click on the "reset"-button to reset the calculation.
Example: What are the polar coordinates of the point with the cartesian coordinates x=3 und y=5 ? After a click with the mouse on any free space of the window or the "calculate"-button you can read the result. The radius (the distance between the origin and the point) is 5.831. The angle between the connection origin to point and the abscissa-axis is 59.036°. This value corresponds to 1.0304 radians or 0.32798*π.
