What is the air pressure in Chongqing?

The atmospheric pressure in Chongqing is about 100kpa.

In physics, the annual average atmospheric pressure at sea level with latitude of 45 degrees (that is, the altitude is zero) is defined as 1 standard atmospheric pressure (atm).

The standard atmospheric pressure is 760mmHg, that is, there is a force of about 1.0336 kg per square centimeter on the flat ground. It is expressed by pa: a standard atmospheric pressure = (1.01325×105) PA = (1.01325×/02) kPa.

Extended data:

Because the mass of the atmosphere is denser and thinner as it gets closer to the ground, the closer it gets to the ground, the greater the pressure changes with height. For example, at the ground level, for every rise of 100 m, the air pressure will drop by about 10 mbar.

At the height of 5 ~ 6 kilometers, the air pressure drops by about 7 mbar per 100 meter; At the altitude of 9 ~ 10 km, the air pressure will only drop by about 5 mbar for every rise of 100 m.

The air pressure has been changing. Under normal circumstances, the air pressure rises every morning and falls in the afternoon; The air pressure is the highest in winter and the lowest in summer.
