    Or:
    Square root of height of eye x 0.97 (in feet)
     Square root of height of eye x 1.76 (in metres)

    You can see how close Frank's approximation of square root of height of eye (in feet) is - as close as 0.97 is to 1.00.  If you are using whole minutes of arc only, then its the same correction (3 minutes of arc) between 6 and 13 feet of elevation.
