About Converting mmHgs to KSI
mmHg and KSI both show up on pressure gauges — psi is standard on US tire and tool specifications, while bar is the everyday pressure unit across most of the rest of the world. Specifically: Millimeters of mercury at standard gravity, and kips per square inch.
Formula
ksi = mmhgs × 0.0000193367774595
This factor comes from each unit's defined relationship to the category's base unit: 1 mmhg equals 133.322387415 base units, and 1 ksi equals 6894757.29317 base units, so dividing one by the other gives the direct mmhg-to-ksi factor of 0.0000193367774595.
Simple example
1 mmHg × 0.00001933677746 = 0.0000193368 ksi
1 mmhg = 0.0000193368 ksi.
Real-world example
35 mmHg × 0.00001933677746 = 0.0006767872 ksi
35 mmhgs = 0.0006767872 ksi.

Frequently asked questions
How many ksi are in 1 mmhg?
1 mmhg equals 0.0000193368 ksi, using the exact defined conversion factor rather than an estimate.
How do I convert mmhg to ksi?
Multiply the mmhg value by 0.00001933677746. The converter above does this instantly to whatever precision you set.
How do I convert ksi back to mmhg?
Use the reverse factor: 1 ksi equals 51,714.9252 mmhgs. You can also use the swap control in the converter above to flip the direction instantly.
What is a mmhg?
mmHg (mmHg) is a unit of pressure.
What is a ksi?
KSI (ksi) is a unit of pressure.
Is the mmhg to ksi conversion exact?
Yes. Both mmhg and ksi are defined by fixed standards rather than physical artifacts, so the factor of 0.00001933677746 used above is exact to as many digits as you choose to display.
