Graphing Polar Calculator
A calculator that converts polar coordinates (r, θ) to Cartesian coordinates (x, y) and plots them on a graph. Enter the radius and angle in degrees or radians to see the point.

How to Use the Graphing Polar Calculator
- Enter the Radius (r) – Type a numeric value (e.g.,
5) into the Radius field. This is the distance from the origin. - Enter the Angle (θ) – Type a numeric value (e.g.,
45) into the Angle field. This is the direction from the positive x-axis. - Choose the Angle Unit – Select either Degrees (default) or Radians from the dropdown. The calculator automatically converts degrees to radians for the math.
- Click "Plot" – Press the blue button to compute the Cartesian coordinates and display the point on the graph.
- Read the Results – The Cartesian Coordinates box shows the x and y values (rounded to 2 decimals). The canvas draws the point with its coordinates labeled.
Tip: The graph uses a scale of 20 pixels per unit, with the origin at the center. Negative radii or angles are supported. If you see an error, ensure both inputs are valid numbers.

Frequently Asked Questions
A polar coordinate system uses a radius (distance from origin) and an angle from the positive x-axis to locate a point.
Use the formulas x = r * cos(θ) and y = r * sin(θ), where θ is in radians. Our calculator does this for you.
Yes, select your preferred angle unit before plotting.
