Best Answer: It depends on your height above the surface of the water. where h is the height above ground or sea level (in meters) of the eye of the observer. For an observer standing at sea level with h = 1.70 metres (5 ft 7 in) (average eye-level height), the horizon is at a distance of 4.7 kilometres (2.9 mi).
1.17 times the square root of your height of eye = Distance to the horizon in nautical miles. Quizmonster. If you're standing at the water's edge, the horizon is about 3 miles away.If you click here that will link you to a web-page which has a handy computer version that helps you work it out.All you do is put the height of your eye relative to the water's edge into the slot and click on 'Compute'.sing this, the distance to the horizon is: SQRT (h+2rh). Using feet throughout (for a six foot eye height) the calculation becomes: SQRT (6+(2*21120000*6) = 15920 feet. Divide this by 5,280 (feet in a mile) and you get 3.01 miles. matt_london s formula is a boiled down version of this one.
