Degrees to Radians Converter — Compass Bearings & Robotics Kinematics

Converting degrees to radians prepares physical angle measurements for programmatic computation in robotics inverse kinematics, game development physics engines, and JavaScript trigonometry. Standard trigonometric functions (`Math.sin()`, `Math.cos()`, `Math.atan2()`) mandate input arguments in radians. Multiplying degrees by $pi/180$ translates surveyor azimuths and robotic joint rotations into radians.

Tutorial

How to Use

01
Enter the angle in degrees (°).
02
The engine multiplies by π and divides by 180 to output exact radians (rad).
03
Examine common angles (30°, 45°, 90°, 180°, 270°, 360°) with exact fractional π equivalents.
04
Copy the radian value directly into your code (Math.sin(angleInRadians)).

Tips & Best Practices

💡
In JavaScript or Python: const radians = degrees * (Math.PI / 180).
💡
45 degrees is π/4 radians (0.7854 rad); 90 degrees is π/2 radians (1.5708 rad).
