English units used for air pressure include:
- pounds per square inch (PSI)
- inches of mercury

- blood pressure - measured in millimeters of mercury
The term atmosphere has sometimes been used by Chemists and Physicists as a unit of pressure. Example: one atmosphere of pressure is the pressure exerted on objects by the atmospheric gasses, air (principally 21% oxygen and 79% nitrogen), at sea level of approximately 14.7 pounds per square inch.
