Convert an angle from degrees minutes and seconds to radian form

The video tutorial explains how to convert time in minutes and seconds into decimal form and then convert degrees into radians. It begins with a discussion on the inconvenience of using minutes and seconds in calculations and the need to convert them into decimal form. The tutorial then demonstrates the calculation process, resulting in a decimal value. Following this, the video covers the conversion of degrees to radians, explaining the use of π/180 in the conversion formula. The tutorial concludes with a practical example, providing a rounded radian value.

Explain why π/180 is used for converting degrees to radians.

What is the final result when converting 75.322 degrees to radians?
