Rendered to 6 significant figures.
Formula
Formula
bar = Pa × 1e-5
Multiply any value in pascals by 1e-5 to obtain the value in bar.
Worked example
Convert 100000 Pa to bar.
- 01Start with 100000 Pa.
- 02Multiply by the conversion factor: 100000 × 1e-5 = 1 bar.
Result100000 Pa = 1 bar

FAQ
What is the conversion factor from Pa to bar?
1 Pa equals 1e-5 bar. To convert, multiply the value in pascals by 1e-5.
How do I convert 1 Pa to bar?
1 Pa = 1e-5 bar. For any value, multiply by 1e-5.
How do I convert bar back to Pa?
Divide by the same factor — or equivalently, multiply by 100000. So 1 bar = 100000 Pa.
When would I need to convert pascal to bar?
Pressure conversions between Pa and bar 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).
