FAQ
What is the conversion factor from inHg to dyn/cm²?
1 inHg equals 33863.89 dyn/cm². To convert, multiply the value in inches of mercury (0 °C) by 33863.89.
How do I convert 1 inHg to dyn/cm²?
1 inHg = 33863.9 dyn/cm². For any value, multiply by 33863.89.
How do I convert dyn/cm² back to inHg?
Divide by the same factor — or equivalently, multiply by 2.952998e-5. So 1 dyn/cm² = 2.953e-5 inHg.
When would I need to convert inch of mercury (0 °C) to dyne per square centimetre?
Pressure conversions between inHg and dyn/cm² 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).
