Convert an angle from degrees to radians

The video tutorial explains how to convert degrees to radians by using the ratio of π to 180 degrees. It demonstrates the process of multiplying degrees by π/180 to cancel out the degrees and simplify the expression to radians. The example provided shows how 120 degrees is converted to 2/3 π radians, emphasizing the importance of understanding the equivalence between degrees and radians for accurate measurement.
