Degrees vs. Radians: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on January 25, 2024
Degrees and radians are two units for measuring angles; degrees divide a circle into 360 parts, while radians use the radius to measure around a circle, equating to about 57.3 degrees.

Key Differences

Degrees are a measure of angles where a full circle is divided into 360 equal parts. Each part is one degree. In contrast, radians offer a different approach, defining angles based on the radius of the circle. One radian is the angle created when the arc length equals the radius.

The concept of degrees is historically older and more familiar in everyday contexts. It is widely used in various fields like navigation and geometry. Radians, however, are more common in higher mathematics and physics as they provide a direct relationship between the angle and the arc length.

When measuring in degrees, simple fractions of a circle, like a quarter or half, are easily represented (90° and 180°, respectively). Radians, on the other hand, express these fractions in terms of π, with π radians being equivalent to 180 degrees, making them more intuitive in mathematical analysis.
