What is the normal air?
The pressure of normal air, if the standard atmospheric pressure is used as the reference, is usually 1 standard atmospheric pressure (atm). 1 standard atmospheric pressure is approximately equal to 101325 Pascals (Pa). Since 1 megapa (MPa) equals 1000,000 Pascals (Pa), the standard atmospheric pressure can be converted to 0.1013 MPa.
In summary, the pressure of normal air is about 0.1013 MPa, under standard atmospheric conditions. This is the average atmospheric pressure value at sea level and is also the internationally recognized standard atmospheric pressure value. It should be noted that the air pressure under actual meteorological conditions may change, and this value is an average or standard value.
