Radian vs. Degree: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on January 8, 2024
Radian is a unit of angular measure in the metric system where the angle is defined by the arc length per radius, while degree is a unit of angular measure equal to 1/360th of a complete circle.

Key Differences

A radian measures angles based on the radius of a circle, where one radian is the angle created when the arc length equals the radius of the circle. Degrees, alternatively, divide a circle into 360 equal parts, with each part representing one degree.

Conversion between radians and degrees is a common practice in various scientific and engineering fields, underscoring their interrelatedness despite different applications. Radians are often preferred in theoretical and analytical work for their mathematical efficiency, while degrees remain popular for their simplicity and historical usage.
