About Converting Torrs to Femtopascals
Torr and Femtopascal 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 femtopascal is 1e-15 pascal units.
Formula
femtopascals = torrs × 1.333224e+17
This factor comes from each unit's defined relationship to the category's base unit: 1 torr equals 133.322368421 base units, and 1 femtopascal equals 1e-15 base units, so dividing one by the other gives the direct torr-to-femtopascal factor of 1.333224e+17.
Simple example
1 Torr × 1.333224e+17 = 1.333224e+17 fPa
1 torr = 1.333224e+17 femtopascals.
Real-world example
35 Torr × 1.333224e+17 = 4.666283e+18 fPa
35 torrs = 4.666283e+18 femtopascals.

Frequently asked questions
How many femtopascals are in 1 torr?
1 torr equals 1.333224e+17 femtopascals, using the exact defined conversion factor rather than an estimate.
How do I convert torr to femtopascal?
Multiply the torr value by 1.333224e+17. The converter above does this instantly to whatever precision you set.
How do I convert femtopascal back to torr?
Use the reverse factor: 1 femtopascal equals 7.500617e-18 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 femtopascal?
Femtopascal (fPa) is a unit of pressure.
Is the torr to femtopascal conversion exact?
Yes. Both torr and femtopascal are defined by fixed standards rather than physical artifacts, so the factor of 1.333224e+17 used above is exact to as many digits as you choose to display.
