Polar to Cartesian Calculator

Convert polar coordinates (r, theta) to 2D Cartesian (x, y) using x = r times cos(theta), y = r times sin(theta). Accepts degrees or radians.

Frequently Asked Questions

How do you convert polar to Cartesian?

x equals r times cosine theta. y equals r times sine theta. Make sure theta is in the right unit (radians for the standard math functions).

Why convert at all?

Different problems are easier in different coordinates. Circular problems are easier in polar; rectangular grids and linear transformations are easier in Cartesian.

Does theta have to be positive?

No. Negative angles measure clockwise from the positive x-axis. The conversion formulas still work.
