FAQ

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