I want to include in my watchface a subdial that shows the battery %, something similar to what appears in the image. The problem is that I can’t find the relationship between the % of battery and the degrees, to enter it in the ‘Angle’ section of the dial. When the percentage is 75 the angle should be 0º, % 50 → 90º, %25 ->180º. And at the ends, %100 → 300º and %0-> 240º. Could someone give me an idea?
