AI overview

A radian is the standard unit for measuring angles in mathematics and the International System of Units, defined as the angle created at the center of a circle when an arc length equals the radius of that circle. Radians matter because they're the default unit for angles in mathematical work, making calculations and formulas simpler and more consistent across science and engineering.
