If at the top of a hill 50m high pressure = 758mm, then what is it equal to at the bottom?

In order to correctly perform all calculations, it is necessary to remember the basic rule of changing atmospheric pressure with decreasing altitude. With a descent for every 10 meters, atmospheric pressure rises by 1 mm Hg. Based on this, it can be determined that atmospheric pressure will change in this way:

50 ÷ 10 = 5 mm Hg

Now let’s calculate what atmospheric pressure will be at the foot of the hill.

758 + 5 = 763 mm Hg

Consequently, at the foot of the hill, atmospheric pressure will show 763 mm Hg.
