How to convert atmospheres to PSI

To convert atmospheres to PSI, multiply by 14.6959. For example, 2 atm × 14.6959 = 29.392 PSI. Going the other way, divide PSI by 14.6959 to get atmospheres.

To convert atmospheres to bar, multiply by 1.01325. So 2 atm × 1.01325 = 2.027 bar.

1 atmosphere (atm) = 14.6959 PSI = 1.01325 bar = 101.325 kPa. Standard atmospheric pressure is the average air pressure at sea level. It is used as a reference point in science, diving, and industrial applications.

Frequently asked questions

How many PSI is 1 atmosphere?
1 atmosphere = 14.6959 PSI = 1.01325 bar = 101.325 kPa.
What is standard atmospheric pressure?
Standard atmospheric pressure = 1 atm = 14.696 PSI = 1.01325 bar = 101.325 kPa = 760 mmHg. This is the average air pressure at sea level.
How many atmospheres is 30 PSI?
30 PSI = 2.041 atm. Calculation: 30 ÷ 14.6959 = 2.041 atm. This is a typical car tire pressure.
How deep can you dive in atmospheres?
Pressure increases by 1 atm for every 10 meters of water depth. At 30m depth the pressure is 4 atm = 58.8 PSI. Recreational divers typically dive to 30-40 meters maximum.
How many atm is 2 bar?
2 bar = 1.9738 atm. Calculation: 2 ÷ 1.01325 = 1.974 atm.
