How to convert atmospheres to bar

To convert atmospheres to bar, multiply by 1.01325. For example, 2 atm × 1.01325 = 2.0265 bar. Going the other way, divide bar by 1.01325 to get atmospheres.

To convert atmospheres to PSI, multiply by 14.696. So 2 atm × 14.696 = 29.392 PSI.

1 atm = 1.01325 bar = 14.696 PSI = 101,325 Pa. Atmospheres are used in chemistry, physics, and scuba diving. Bar is used in meteorology, industry, and European tire pressure ratings.

Frequently asked questions

How many bar is 1 atmosphere?
1 atm = 1.01325 bar = 14.696 PSI = 101,325 Pa.
How many atmospheres is 1 bar?
1 bar = 0.986923 atm = 14.504 PSI = 100,000 Pa.
How many bar is 3 atmospheres?
3 atm = 3.040 bar = 44.088 PSI. Calculation: 3 × 1.01325 = 3.040 bar.
What depth is 2 atm underwater?
2 atm of absolute pressure occurs at about 10 meters underwater. The total pressure at 10m depth is 2 atm — 1 atm from the atmosphere plus 1 atm from the water.
How many bar is 2.5 atmospheres?
2.5 atm = 2.533 bar = 36.74 PSI. Calculation: 2.5 × 1.01325 = 2.533 bar.
