Convert Radian to Degree
Unit definitions
Radian
The radian is the unit of angle in the SI. A full circle is $2\pi$ radians, where $\pi$ is approximately $3.141\,592\,653\,589\,793$.
Degree
The degree is a unit of angle commonly used in daily life. One full circle consists of $360$ degrees.
How to convert Radian to Degree
$$\text{Angle}_{\text{°}} = \frac{\text{Angle}_{\text{rad}}}{3.141592653589793} \cdot 180$$
Examples
Example 1
Convert $25.0\ \text{rad}$ to $\text{°}$.
$$\text{Angle}_{\text{°}} = \frac{25.0}{3.141592653589793} \cdot 180$$
$$\text{Angle}_{\text{°}} = 1432.394488$$
$$\therefore \ 25.0\ \text{rad} = 1432.394488 \ \text{°}$$
Example 2
Convert $80.0\ \text{rad}$ to $\text{°}$.
$$\text{Angle}_{\text{°}} = \frac{80.0}{3.141592653589793} \cdot 180$$
$$\text{Angle}_{\text{°}} = 4583.662361$$
$$\therefore \ 80.0\ \text{rad} = 4583.662361 \ \text{°}$$
Example 3
Convert $100.0\ \text{rad}$ to $\text{°}$.
$$\text{Angle}_{\text{°}} = \frac{100.0}{3.141592653589793} \cdot 180$$
$$\text{Angle}_{\text{°}} = 5729.577951$$
$$\therefore \ 100.0\ \text{rad} = 5729.577951 \ \text{°}$$
Example 4
Convert $145.0\ \text{rad}$ to $\text{°}$.
$$\text{Angle}_{\text{°}} = \frac{145.0}{3.141592653589793} \cdot 180$$
$$\text{Angle}_{\text{°}} = 8307.888029$$
$$\therefore \ 145.0\ \text{rad} = 8307.888029 \ \text{°}$$
Example 5
Convert $165.0\ \text{rad}$ to $\text{°}$.
$$\text{Angle}_{\text{°}} = \frac{165.0}{3.141592653589793} \cdot 180$$
$$\text{Angle}_{\text{°}} = 9453.80362$$
$$\therefore \ 165.0\ \text{rad} = 9453.80362 \ \text{°}$$
