Formula

Formula
ksi = mmHg × 1.933678e-5

Multiply any value in millimetres of mercury by 1.933678e-5 to obtain the value in kilopounds-force per square inch.

Worked example

Convert 1000 mmHg to ksi.

  1. 01Start with 1000 mmHg.
  2. 02Multiply by the conversion factor: 1000 × 1.933678e-5 = 0.0193368 ksi.
Result1000 mmHg = 0.0193368 ksi

FAQ

What is the conversion factor from mmHg to ksi?
1 mmHg equals 1.933678e-5 ksi. To convert, multiply the value in millimetres of mercury by 1.933678e-5.
How do I convert 1 mmHg to ksi?
1 mmHg = 1.93368e-5 ksi. For any value, multiply by 1.933678e-5.
How do I convert ksi back to mmHg?
Divide by the same factor — or equivalently, multiply by 51714.93. So 1 ksi = 51714.9 mmHg.
When would I need to convert millimetre of mercury to kilopound-force per square inch?
Pressure conversions between mmHg and ksi 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).
