FAQ
What is the conversion factor from ksi to bar?
1 ksi equals 68.94757 bar. To convert, multiply the value in kilopounds-force per square inch by 68.94757.
How do I convert 1 ksi to bar?
1 ksi = 68.9476 bar. For any value, multiply by 68.94757.
How do I convert bar back to ksi?
Divide by the same factor — or equivalently, multiply by 0.01450377. So 1 bar = 0.0145038 ksi.
When would I need to convert kilopound-force per square inch to bar?
Pressure conversions between ksi 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).
