1 bar = 0.986923 atm · 1 bar = 14.5038 PSI

How to convert bar to atmospheres

To convert bar to atmospheres, multiply by 0.986923. For example, 2 bar × 0.986923 = 1.974 atm. Going the other way, multiply atmospheres by 1.01325 to get bar.

To convert bar to PSI, multiply by 14.5038. So 1 bar × 14.5038 = 14.504 PSI.

1 bar = 0.986923 atm = 14.5038 PSI = 100,000 Pa. 1 atm = 1.01325 bar = 14.696 PSI = 101,325 Pa. Bar and atmospheres are very close in value — 1 bar is about 1.3% less than 1 atmosphere.

Frequently asked questions

How many atmospheres is 1 bar?
1 bar = 0.986923 atm = 14.5038 PSI = 100,000 Pa. One bar is about 1.3% less than 1 standard atmosphere.
How many bar is 1 atmosphere?
1 atm = 1.01325 bar = 14.696 PSI = 101,325 Pa.
What is the difference between bar and atmosphere?
1 bar = 100,000 Pa. 1 atm = 101,325 Pa. They are very close but not equal. Bar is used in meteorology and industry while atm is used in chemistry and physics.
How many bar is 2 atmospheres?
2 atm = 2.0265 bar = 29.392 PSI. Calculation: 2 × 1.01325 = 2.0265 bar.
How deep underwater is 2 bar?
2 bar = approximately 10 meters underwater. Water pressure increases by about 1 bar for every 10 meters of depth.
