What is is normal atmospheric pressure
Answers
Answer:
The standard, or near-average, atmospheric pressure at sea level on the Earth is 1013.25 millibars, or about 14.7 pounds per square inch. ... If you live at a higher altitude, the pressure will be lower since there is less air above weighing down upon you.

Standard air pressure at sea level is 1 atmosphere, or 1 atm. This is the standard value, but it will not always equal this value due to changes in weather.
1 atm = 760 mm of Hg or 76 cm of Mercury.
