The Conversion Formula
To convert atmospheres to psi, multiply the value by the conversion factor: 1 atm = 14.6959 psi. For a worked example, suppose you need to convert 25 atm to psi: 25 × 14.6959 = 367.4 psi. To convert in the opposite direction, divide by 14.6959, or equivalently multiply by 0.068046.
About atmospheres
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. atmospheres are commonly used in Diving depth (1 atm per 10m), Chemistry (Standard Temp/Pressure), Hyperbaric chambers, and Spacecraft engineering, Altitude simulation.
At sea level, the air pressure is exactly 1 atm.
About 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. psi are commonly used in Tire pressure (US), Blood pressure (rarely), Scuba tanks (US), and Industrial pumps, Paintball tanks.
A standard car tire is inflated to 30-35 psi.
When Would You Convert atmospheres to psi?
Converting between atmospheres and psi is one of the most common pressure conversions. You might need this conversion when working with international specifications, following instructions written for a different measurement system, or comparing values across different standards. Having the conversion factor (1 atm = 14.6959 psi) memorized or bookmarked can save time in professional and everyday contexts alike.
