At sea level, atmospheric pressure is about 1,000 mb (100 kPa). At the top of Mt. Everest —a height of 29,032 feet (8.85 kilometers)—pressure drops to about 300 mb (30 kPa). The air is so thin at an altitude of 31 miles (50 kilometers) that it exerts a pressure of only 1 mb (0.1 kPa).

The greatest air pressure pressing down on our bodies is at sea level. Scientists use the term one atmosphere to describe the pressure at sea level. Normal pressure at sea level is 14.7 psi (pounds per square inch). Normal pressure at sea level measures 29.9213 inches (760 mm) on barometers.
MAX: Atmospheric pressure is the force exerted by the air on the earth. MAX: It's highest at sea level and decreases as you go up. Low-pressure areas create rain and storms while the...
19 paź 2023 · An atmosphere (atm) is a unit of measurement equal to the average air pressure at sea level at a temperature of 15 degrees Celsius (59 degrees Fahrenheit). One atmosphere is 1,013 millibars, or 760 millimeters (29.92 inches) of mercury. Atmospheric pressure drops as altitude increases.
The normal air pressure at sea level ranges from 800 mb to 1050 mb. Quick Facts: – The first ever barometer was invented by Evangelista Toricelli in 1644. On weather maps, air pressure is shown with line called isobars. These lines join places of equal pressure together. Zones with high pressure are called anticyclones and zones with low ...
