Scuba diving — depth pressure in atmospheres Aviation altitude pressure effects Laboratory gas pressure referencing Scientific pressure calculations

About PSI and Atmospheres

One atmosphere equals approximately 14.696 PSI. The atmosphere (atm) is a natural pressure unit based on Earth's average atmospheric pressure at sea level. Scuba divers use atmospheres to calculate pressure at depth — every 10 meters underwater adds 1 atm. Altitude effects on aviation and physiology are often discussed in atmospheres. Laboratory equipment and gas cylinder pressures in PSI need atm conversion for scientific applications where atmospheric pressure is the reference point.
