WebTo determine the precise distance between you and the horizon, you must know two values: your vision level and the Earth's radius. The following is the equation a = √ [ (r + h)² - r²] Where, a = distance of the horizon h = eyesight level above mean sea level r = Erath's radius, which is 6371 km or 3959 miles WebAbout 9.8 inches per mile. Trust his (that other guy's) answer, I have a paper covered with angles and sins and tans and stuff and had to do it about 5 times before I got what I think is the right answer. Mine is based on the idea that the earth descends at an angle of 0.008957 degrees per km (at the equator).
