Conversion Formula
The relationship between radians and degrees is defined by the following formula:
Formula
Degrees = Radians × (180/π)
This formula comes from the fact that a full circle is 360 degrees or 2π radians. Therefore, to convert radians to degrees, you multiply the radian value by 180 divided by π (pi).
The value of π (pi) used in this calculation is approximately 3.141592653589793.
Common Uses of Degrees
Degrees are commonly used in various fields:
- Everyday life: Degrees are used to measure angles in construction, navigation, and various practical applications.
