What pressure will be at an altitude of 300 m if at sea level it is equal to 760 mm Hg?

Since with an increase in altitude by 10 meters, atmospheric pressure decreases by 1 millimeter of mercury, the pressure at an altitude of 300 meters above sea level will be:

760 – (300/10) = 760 – 30 = 730 mm Hg


At an altitude of 300 meters above sea level, the pressure is 730 mm Hg.
