Enter the two positions in the boxes below (Position A for start, Position B for destination). Data needs to be entered in the format shown, but the calculator will convert this to the standard geo formats (Degrees, Decimal Degrees, & UTM) and will also compute the altitude at the location.
Two results will be displayed - showing the great-circle distance between two points, and the initial compass bearing/heading from the origin to the destination. This distance may be very much different from the actual travel distance as it is the shortest straight line distance that factors the variations of the earth's curvature.
