Understanding Degrees and Radians

Degrees and radians are both units used to measure angles. A degree (°), the more common unit, is based on dividing a full circle into 360 equal parts. Radians, on the other hand, are based on the radius of a circle. One radian is the angle subtended at the center of a circle by an arc whose length is equal to the radius of the circle.

Formula: To convert degrees to radians, you multiply the angle in degrees by π / 180.

$$ Radians = Degrees × \frac{\pi}{180} $$

Use Cases: Radians are particularly important in advanced mathematics and physics because they simplify many formulas, especially in calculus and trigonometry. They are the standard unit of angular measure in scientific and mathematical contexts.
