Understanding Angle Conversion

What are Degrees and Radians?

Degrees and radians are units for measuring angles. A degree (°), the more common unit, divides a full circle into 360 parts. A radian (rad) is the angle subtended at the center of a circle by an arc whose length is equal to the radius of the circle.

Formula for Conversion

To convert degrees to radians, we use the formula:

Why Use Radians?

Radians are the standard unit of angular measure in many areas of mathematics and physics, especially in calculus and higher-level mathematics. They simplify many formulas and provide a more natural way to work with angles in mathematical contexts.
