About Converting Torrs to Gigapascals
Torr and Gigapascal 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: 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
35 Torr × 1.333224e-7 = 0.0000046663 GPa
35 torrs = 0.0000046663 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 pressure.
What is a gigapascal?
Gigapascal (GPa) is a unit of pressure.
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.
