**Step 1 :** Read the given problem and observe whether the given angle is in degree or radians.

**Step 2 :** If the given angle is in radians, it can be converted into degree using formula

Degree = $\frac{radians \times 180^o}{\pi}$

If the given angle is in degree, it can be converted into radius using formula

Radian = $\frac{Degree \times \pi}{180^o}$

Substitute the given angle in above formula and get the conversion.
