Enter a value in either PSI or BAR and the second unit will be calculated automatically.

Formula: 1 bar = 14.5037738 psi - 1 psi = 0.0689476 bar

How much is 1 PSI in bar?

1 PSI is equivalent to 0.06895 bar. 

What is PSI and bar?

PSI (pounds per square inch) and bar are units of pressure. PSI is mainly used in the US and the UK, while bar is more common in Europe. To compare pressure values between different systems, you can easily convert between these two units using formulas or tables. 

How to convert between PSI and bar?

To convert between PSI and bar, the following formulas are used:   

PSI to bar: bar = PSI × 0.06895   

Bar to PSI: PSI = bar × 14.5038   

Example:   

100 PSI = 6,895 bar   

5 bar = 72,519 PSI
