About Converting Torrs to Gigapascals
Torr and Gigapascal 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 gigapascal is 1000000000 pascal units.
Formula
gigapascals = torrs × 1.333224e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 torr equals 133.322368421 base units, and 1 gigapascal equals 1000000000 base units, so dividing one by the other gives the direct torr-to-gigapascal factor of 1.333224e-7.
Simple example
1 Torr × 1.333224e-7 = 1.333224e-7 GPa
1 torr = 1.333224e-7 gigapascals.
Real-world example
100 Torr × 1.333224e-7 = 0.0000133322 GPa
100 torrs = 0.0000133322 gigapascals.

Frequently asked questions
How many gigapascals are in 1 torr?
1 torr equals 1.333224e-7 gigapascals, using the exact defined conversion factor rather than an estimate.
How do I convert torr to gigapascal?
Multiply the torr value by 1.333224e-7. The converter above does this instantly to whatever precision you set.
How do I convert gigapascal back to torr?
Use the reverse factor: 1 gigapascal equals 7,500,616.827 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 gigapascal?
Gigapascal (GPa) is a unit of engineering.
Is the torr to gigapascal conversion exact?
Yes. Both torr and gigapascal are defined by fixed standards rather than physical artifacts, so the factor of 1.333224e-7 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.
