Polar to Rectangular Coordinate Converter
Convert between polar and rectangular coordinate systems with multiple formats
About this calculator
The Polar to Rectangular Coordinate Converter transforms coordinates between polar (r, θ) and rectangular (x, y) coordinate systems. This calculator is essential for students, engineers, and mathematicians working with trigonometry, complex numbers, navigation, or physics problems. It supports multiple angle formats including degrees, radians, and gradians, making it versatile for various applications. The tool provides instant, accurate conversions that save time on manual calculations and reduce computational errors in mathematical and engineering work.
How to use
Enter your coordinates in either polar format (radius and angle) or rectangular format (x and y values). Select your preferred angle unit (degrees, radians, or gradians) from the dropdown menu. Click the convert button to instantly see the equivalent coordinates in the opposite system with precise calculations.
Frequently asked questions
What's the difference between polar and rectangular coordinates?
Polar coordinates use radius and angle (r, θ) from origin, while rectangular coordinates use horizontal and vertical distances (x, y) on a grid.
Can I convert angles in different units?
Yes, the calculator supports degrees, radians, and gradians. Simply select your preferred unit from the dropdown menu before converting.
When should I use polar vs rectangular coordinates?
Use polar for circular motion, rotation problems, and navigation. Use rectangular for linear calculations, graphing functions, and standard algebraic operations.
