FAQ

What is the conversion factor from mmHg to kgf/mm²?
1 mmHg equals 1.35951e-5 kgf/mm². To convert, multiply the value in millimetres of mercury by 1.35951e-5.
How do I convert 1 mmHg to kgf/mm²?
1 mmHg = 1.35951e-5 kgf/mm². For any value, multiply by 1.35951e-5.
How do I convert kgf/mm² back to mmHg?
Divide by the same factor — or equivalently, multiply by 73555.91. So 1 kgf/mm² = 73555.9 mmHg.
When would I need to convert millimetre of mercury to kilogram-force per square millimetre?
Pressure conversions between mmHg 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).
