Frequently asked questions
How many psi in a bar?
1 bar = 100,000 Pa = 14.504 psi ≈ 0.987 atm. 1 atmosphere = 101,325 Pa = 14.696 psi. 1 psi ≈ 6,895 Pa.
How do the linked fields work?
All units share the pascal as a base. Type a value in one field and the others update instantly.
Bar or atmosphere?
Very close: 1 bar = exactly 100,000 Pa, while 1 atm = 101,325 Pa (standard atmospheric pressure). The gap is about 1.3%.
