About Atmospheres and PSI

One atmosphere equals exactly 14.696 PSI. Standard atmospheric pressure is 1 atm at sea level, equivalent to 14.696 PSI. This conversion is used in chemistry for gas law calculations (Boyle's Law, ideal gas law), diving for underwater pressure calculations, and aviation for altitude pressure effects. A scuba tank at 3000 PSI contains about 204 atmospheres of compressed air. Autoclave sterilizers operate at specific atmospheric pressures that translate to PSI for equipment calibration.
