Convert pascals, bars, PSI, atmospheres, mercury columns, water columns, and engineering pressure units.
Context values
Some unit families need one extra value for a physically accurate result.
Megapascal is 1000000 pascal units.
Result = input x 133.3223874 / 1e+6.
Pressure uses the pascal as the base unit.

About Converting mmHgs to Megapascals
mmHg and Megapascal 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 megapascal is 1000000 pascal units.
Formula
megapascals = mmhgs × 0.000133322387415
This factor comes from each unit's defined relationship to the category's base unit: 1 mmhg equals 133.322387415 base units, and 1 megapascal equals 1000000 base units, so dividing one by the other gives the direct mmhg-to-megapascal factor of 0.000133322387415.
Simple example
1 mmHg × 0.0001333223874 = 0.0001333224 MPa
1 mmhg = 0.0001333224 megapascals.
Real-world example
35 mmHg × 0.0001333223874 = 0.0046662836 MPa
35 mmhgs = 0.0046662836 megapascals.

Frequently asked questions
How many megapascals are in 1 mmhg?
1 mmhg equals 0.0001333224 megapascals, using the exact defined conversion factor rather than an estimate.
How do I convert mmhg to megapascal?
Multiply the mmhg value by 0.0001333223874. The converter above does this instantly to whatever precision you set.
How do I convert megapascal back to mmhg?
Use the reverse factor: 1 megapascal equals 7,500.615758 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 megapascal?
Megapascal (MPa) is a unit of pressure.
Is the mmhg to megapascal conversion exact?
Yes. Both mmhg and megapascal are defined by fixed standards rather than physical artifacts, so the factor of 0.0001333223874 used above is exact to as many digits as you choose to display.
