A pitcher's arm rotates at a speed of 7 degrees per millisecond (degrees/ms)

At what speed does the pitcher's arm rotate in degrees/s?

To solve this problem, all we have to do is to use a conversion factor to convert millisecond into seconds. We know that there are 1000 milliseconds in a second, therefore:

pitcher’s arm rotation = 7 degrees / millisecond * (1000 milliseconds / second)

pitcher’s arm rotation = 7,000 degrees / second
