How to Convert atmospheres to psi
To convert atmospheres to psi, multiply the value by the conversion factor:
Reverse: 14.6959 psi = 0.999997 atmospheres
Reverse: 14.6959 psi = 0.999997 atmospheres
psi to atmospheres converterAbout These Units
atmospheres (atm)
The standard atmosphere (atm) represents the average pressure exerted by Earth's atmosphere at sea level. It was originally defined by the height of mercury in a barometer (760 mm). It is the most intuitive unit for understanding pressure: 2 atm means double the pressure you feel standing on the beach.
At sea level, the air pressure is exactly 1 atm.
Commonly used in: Diving depth (1 atm per 10m), Chemistry (Standard Temp/Pressure), Hyperbaric chambers, Spacecraft engineering, Altitude simulation.
psi (psi)
PSI stands for 'Pounds per Square Inch'. It is the standard unit for pressure in the United States. It measures how many pounds of force are pressing on every square inch of surface. It is the unit every American driver looks for when filling their tires.
A standard car tire is inflated to 30-35 psi.
Commonly used in: Tire pressure (US), Blood pressure (rarely), Scuba tanks (US), Industrial pumps, Paintball tanks.
