Formula
Formula
Pa = bar × 100000
Multiply any value in bar by 100000 to obtain the value in pascals.
Worked example
Convert 1 bar to Pa.
- 01Start with 1 bar.
- 02Multiply by the conversion factor: 1 × 100000 = 100000 Pa.
Result1 bar = 100000 Pa

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