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.
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).

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.
Air Pressure. Air pressure is sometimes also called atmospheric pressure. This is the total weight of the air in the atmosphere pushing down on the surface of the earth. Air can be...
Map of global mean air pressure at sea level in July, where high-pressure centers are more pronounced, especially over the North Atlantic and North Pacific oceans. Near Earth’s surface, atmospheric pressure decreases with height at a rate of about 3.5 millibars for every 30 meters (100 feet).
Air Pressure can be defined as the continuous pounding of billions of air molecules as they zoom about. The earth is covered in a layer of air. This layer is not evenly distributed around the globe. Air is light but at ground level huge pressure can be exerted.
