Rectangular to Polar Coordinates Calculator

Convert rectangular coordinates \((x, y)\) to polar coordinates \((R, \theta)\):

\[ R = \sqrt{x^2 + y^2} \]

\[ \theta = \text{atan2}(y, x) \quad \text{(in radians)} \]

\[ \theta_{\text{(deg)}} = \theta \times \frac{180}{\pi} \]

Where \(R\) is the radial distance, and \(\theta\) is the angle in radians or degrees, with range \((-\pi, \pi]\) or \((-180°, 180°]\).

Enter x and y coordinates, then click Calculate.
