What does 1 atm mean in chemistry?

A pressure of 1 atmosphere is equal to the pressure exerted by a column of water that is equal to the weight of about 1 km of water, or about 5.5 trillion pounds. That's about the weight of a mountain worth of water that has been standing on the earth's surface for about 5.5 billion years.

The most commonly used unit for pressure is the bar or atmosphere. A pressurized volume is defined as one that contains 1 atmosphere of pressure. One atmosphere is equal to the force of 1kg of mass at a distance of 1 meter from the center of earth. At this pressure, a column of water 1 meter high would rise to 1 meter.

One atmosphere of pressure is equal to about 0.5 megapascal (or 5.5 megabar) of pressure. One atmosphere is the normal pressure felt when standing on the earth’s surface.

If you’ve been around the lab for any length of time, you’ve probably heard this abbreviation thrown around, especially in discussion of gas laws. But what does it really stand for? It’s an acronym for absolute temperature. It’s a key part of the equation that defines pressure.

The pressure of a gas is equal to the amount of force per unit area that the gas exerts. A column of gas under one atmosphere of pressure has a weight of about 1.01225 lbs. of force per square inch. The atmosphere is defined as the amount of gas surrounding the earth that a person, on average, would experience at sea level. Currently, the standard atmosphere at sea level is equal to about 1.01325 kg of gas. So, while the earth’s
