Is the air pressure 10 16 Pa high or low?

The answer is definitely high, and the change of atmospheric pressure is related to altitude.

The pressure at sea level is called 1 atmospheric pressure, and the value on the mercury barometer is 760 mm high, which is equivalent to the official standard value 10 13.25 hectopascals, which is converted into 10 1.325 kilopascals.

For example, on the Qinghai-Tibet Plateau at an altitude of 3,000 meters, the air pressure is less than 699.9 hectopascals, which is equivalent to less than 69.99 kilopascals, so the air pressure on the plateau is generally very low. On the contrary, the average altitude in Nanning, Guangxi is 79 meters, and the atmospheric pressure 1004 hectopascals is converted into 100.4 kilopascals, which is much higher than that in the plateau.
