About Converting Torrs to Megapascals
Torr and Megapascal both measure a quantity used in structural or mechanical engineering — commonly stress, pressure, force, torque, power, or energy — where converting between the unit conventions used in different regions, industries, or equipment specifications is a routine part of design work. Specifically: A torr is 1/760 standard atmosphere, and megapascal is 1000000 pascal units.
Formula
megapascals = torrs × 0.000133322368421
This factor comes from each unit's defined relationship to the category's base unit: 1 torr equals 133.322368421 base units, and 1 megapascal equals 1000000 base units, so dividing one by the other gives the direct torr-to-megapascal factor of 0.000133322368421.
Simple example
1 Torr × 0.0001333223684 = 0.0001333224 MPa
1 torr = 0.0001333224 megapascals.
Real-world example
100 Torr × 0.0001333223684 = 0.0133322368 MPa
100 torrs = 0.0133322368 megapascals.

Reverse conversion: Megapascal to Torr
0.0001333224 MPa × 7500.616827 = 1.000000237 Torr
0.0001333224 megapascals = 1.000000237 torrs.
torrs = megapascals × 7500.61682704

Frequently asked questions
How many megapascals are in 1 torr?
1 torr equals 0.0001333224 megapascals, using the exact defined conversion factor rather than an estimate.
How do I convert torr to megapascal?
Multiply the torr value by 0.0001333223684. The converter above does this instantly to whatever precision you set.
How do I convert megapascal back to torr?
Use the reverse factor: 1 megapascal equals 7,500.616827 torrs. You can also use the swap control in the converter above to flip the direction instantly.
What is a torr?
Torr (Torr) is a unit of engineering.
What is a megapascal?
Megapascal (MPa) is a unit of engineering.
Is the torr to megapascal conversion exact?
Yes. Both torr and megapascal are defined by fixed standards rather than physical artifacts, so the factor of 0.0001333223684 used above is exact to as many digits as you choose to display.
Why do engineering unit conventions vary so much by region and industry?
Pressure, force, and stress can be expressed in metric (pascal, newton), US customary (psi, pound-force), or older and industry-specific units (atmosphere, torr, kip) depending on the country, industry, and even the equipment manufacturer, which is why engineers routinely need to convert between them when working across specs from different sources.
