About Converting mmHgs to Kilopascals
mmHg and Kilopascal 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 kilopascal is 1000 pascal units.
Formula
kilopascals = mmhgs × 0.133322387415
This factor comes from each unit's defined relationship to the category's base unit: 1 mmhg equals 133.322387415 base units, and 1 kilopascal equals 1000 base units, so dividing one by the other gives the direct mmhg-to-kilopascal factor of 0.133322387415.
Simple example
1 mmHg × 0.1333223874 = 0.1333223874 kPa
1 mmhg = 0.1333223874 kilopascals.
Real-world example
35 mmHg × 0.1333223874 = 4.66628356 kPa
35 mmhgs = 4.66628356 kilopascals.

Frequently asked questions
How many kilopascals are in 1 mmhg?
1 mmhg equals 0.1333223874 kilopascals, using the exact defined conversion factor rather than an estimate.
How do I convert mmhg to kilopascal?
Multiply the mmhg value by 0.1333223874. The converter above does this instantly to whatever precision you set.
How do I convert kilopascal back to mmhg?
Use the reverse factor: 1 kilopascal equals 7.500615758 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 kilopascal?
Kilopascal (kPa) is a unit of pressure.
Is the mmhg to kilopascal conversion exact?
Yes. Both mmhg and kilopascal are defined by fixed standards rather than physical artifacts, so the factor of 0.1333223874 used above is exact to as many digits as you choose to display.
