PSI, pound per square inch.

Or in SI units, Pascals (Pa) - but these are so tiny that you need thousands (kPa) or millions (MPa) of them to get anywhere. Unless you are measuring sound pressure in linear units, in gases or in liquids, then they are too big so you need to use millionths of Pascals (µPa, pron. "micro-Pascal"). For everyday use the Bar is admissible: 1Bar is atmospheric pressure at standard temperature at mean sea-level, and = 100kPa.

1,2,3,4,5,6,7,8,9, that are the units ( i think) well bye!

Chemistry uses both the metric system and the International System (SI) units of measurements. Air pressure equations are measured in atmospheres (ATM) and Pascal's (Pa) for physical chemistry.
The answer to this question is, the Mercury and aneroid barometer
inches in mercury and millibars Barometers .
The measure of the weight of the air above us is called air pressure. Air pressure varies depending on your location.
