What is the atmospheric pressure in normal weather?

The normal weather pressure is 10 1.325kPa, which is the pressure at sea level under standard atmospheric conditions.

A standard atmospheric pressure is specified as follows: the atmospheric pressure at sea level with a temperature of 0℃ and a latitude of 45 degrees is called 1 atmospheric pressure, and the value on the mercury barometer is 760 mm Hg (equivalent to10/3.25 hectopascals).

1 standard atmospheric pressure = 760mmhg = 76cmhg =1.01325x105pa =10.339m water column. 1 standard atmospheric pressure = 10 1325N/㎡. (In the calculation, it is usually 1 standard atmospheric pressure =1.01×105n/㎡). 100 kpa = 0. 1 MPa.
