FAQ
What is the conversion factor from bar to psi?
1 bar equals 14.50377 psi. To convert, multiply the value in bar by 14.50377.
How do I convert 1 bar to psi?
1 bar = 14.5038 psi. For any value, multiply by 14.50377.
How do I convert psi back to bar?
Divide by the same factor — or equivalently, multiply by 0.06894757. So 1 psi = 0.0689476 bar.
When would I need to convert bar to pound-force per square inch?
Pressure conversions between bar and psi are common when working with mixed-vendor instrumentation, when piping codes use different units to process datasheets, or when converting field readings into SI for hydraulic calculations.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
