Units of Pressure: What is an atmosphere?
When talking about pumps and pressure, the term “atmospheres” is a common unit of measure. It is based on atmospheric pressure at sea level.
Converting atmospheres to PSI
An atmosphere (atm) is equivalent to around 14.7 pounds per square inch (PSI).
Atm x 14.7 = PSI
Converting PSI to atmospheres
PSI / 14.7 = atm
