FAQ

What is the conversion factor from inHg to kgf/m²?
1 inHg equals 345.3156 kgf/m². To convert, multiply the value in inches of mercury (0 °C) by 345.3156.
How do I convert 1 inHg to kgf/m²?
1 inHg = 345.316 kgf/m². For any value, multiply by 345.3156.
How do I convert kgf/m² back to inHg?
Divide by the same factor — or equivalently, multiply by 0.002895902. So 1 kgf/m² = 0.0028959 inHg.
When would I need to convert inch of mercury (0 °C) to kilogram-force per square metre?
Pressure conversions between inHg and kgf/m² 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).
