FAQ

What is the conversion factor from kgf/cm² to mmHg?
1 kgf/cm² equals 735.5591 mmHg. To convert, multiply the value in kilograms-force per square centimetre by 735.5591.
How do I convert 1 kgf/cm² to mmHg?
1 kgf/cm² = 735.559 mmHg. For any value, multiply by 735.5591.
How do I convert mmHg back to kgf/cm²?
Divide by the same factor — or equivalently, multiply by 0.00135951. So 1 mmHg = 0.00135951 kgf/cm².
When would I need to convert kilogram-force per square centimetre to millimetre of mercury?
Pressure conversions between kgf/cm² 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).
