Gases are different from solids and liquids. In a sample of gas, the molecules are far apart. The gas molecules also move around and collidewith each other as well as with the walls of the container. These collisions generate pressure. The pressure of a gas can be measured indifferent units. One convenient unit of measure is called the atmosphere (atm) because it is based on atmospheric pressure. At sea level,the average pressure is 1 atm. As you get higher in altitude, the pressure steadily drops until you leave the atmosphere, where the pressureis very close to 0 atm.The table below shows the different commonly used units of measuring gas pressure.

We would use required conversion factors to calculate the pressure in required unit.
