FAQ
What is the conversion factor from hPa to kgf/mm²?
1 hPa equals 1.019716e-5 kgf/mm². To convert, multiply the value in hectopascals by 1.019716e-5.
How do I convert 1 hPa to kgf/mm²?
1 hPa = 1.01972e-5 kgf/mm². For any value, multiply by 1.019716e-5.
How do I convert kgf/mm² back to hPa?
Divide by the same factor — or equivalently, multiply by 98066.5. So 1 kgf/mm² = 98066.5 hPa.
When would I need to convert hectopascal to kilogram-force per square millimetre?
Pressure conversions between hPa and kgf/mm² 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).
