Conversion Formula
1 atm = 101,325 Pa = 14.696 psi
To convert from one pressure unit to another, first convert to the base unit (pascals), then convert to the target unit. For example, to convert psi to bar: multiply the psi value by 6894.76 to get pascals, then divide by 100000 to get bar.
Frequently Asked Questions
How do I convert psi to bar?
Multiply the psi value by 0.0689476. For example, 30 psi = 30 × 0.0689476 = 2.06843 bar.
What is the difference between atm and bar?
1 atmosphere (atm) is defined as 101,325 pascals, while 1 bar is defined as 100,000 pascals. So 1 atm ≈ 1.01325 bar. They are close but not exactly equal.
