About Rectangular to Polar Coordinates
Rectangular to Polar Coordinates is a specialized web application engineered to perform instant, high-precision bidirectional coordinate conversions between 2D Cartesian (x, y) values and polar (r, θ) vectors.
It is designed, developed, and maintained with ❤️ by Shahab Dev.
What Rectangular to Polar Coordinates Converter Does
Engineers, physics researchers, survey technicians, and mathematics students constantly switch between rectangular coordinates and polar angles. Whether calculating vector forces, analyzing AC circuits with phasors, or configuring CNC tool paths, manual conversion is prone to quadrant errors. You can use our interactive rectangular to polar coordinates converter directly on the homepage, or read detailed explanations in our step-by-step math guide. Our tool eliminates manual friction through:
- Quadrant-aware angle calculation using
atan2(y, x)for true geometric direction - Instant toggle between Degrees and Radians
- Dynamic precision controls from 0 to 8 decimal places
- Bidirectional conversion: Rectangular → Polar and Polar → Rectangular
- One-click copy functions and quick scalar step controls
