How it works
Polar to Cartesian: x=r cos θ, y=r sin θ. Reverse: r=hypot(x,y), θ=atan2(y,x) in degrees.
Input definitions
- Direction
- Choose Polar to Cartesian / Cartesian to polar.
- Radius or x
- Enter the value in the labeled unit.
- Angle (degrees) or y
- Enter the value in the labeled unit.

Common questions
How is the origin handled?
The origin has radius zero and no unique angle. The reverse conversion displays zero degrees by convention and explains this limitation.
How does Polar and Cartesian coordinate converter work?
Polar to Cartesian: x=r cos θ, y=r sin θ. Reverse: r=hypot(x,y), θ=atan2(y,x) in degrees.
