Using the Closed Fist Method, if you measure five fingers, what is the elevation?

Explanation:
In the Closed Fist Method you estimate vertical angles by the angular span of your hand at arm’s length. A closed fist across the knuckles covers about 10 degrees of the sky. Five fingers across the hand roughly matches that span, so measuring five fingers corresponds to about 10 degrees of elevation. This is a quick, rough tool for field use when you don’t have a clinometer. Small individual differences in arm length or hand size can shift a degree or two, but 10 degrees is the standard reference for five fingers.
