About Converting Nanopascals to Torrs
Nanopascal and Torr 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: Nanopascal is 1e-9 pascal units, and a torr is 1/760 standard atmosphere.
Formula
torrs = nanopascals × 7.500617e-12
This factor comes from each unit's defined relationship to the category's base unit: 1 nanopascal equals 1e-9 base units, and 1 torr equals 133.322368421 base units, so dividing one by the other gives the direct nanopascal-to-torr factor of 7.500617e-12.
Simple example
1 nPa × 7.500617e-12 = 7.500617e-12 Torr
1 nanopascal = 7.500617e-12 torrs.
Real-world example
35 nPa × 7.500617e-12 = 2.625216e-10 Torr
35 nanopascals = 2.625216e-10 torrs.

Frequently asked questions
How many torrs are in 1 nanopascal?
1 nanopascal equals 7.500617e-12 torrs, using the exact defined conversion factor rather than an estimate.
How do I convert nanopascal to torr?
Multiply the nanopascal value by 7.500617e-12. The converter above does this instantly to whatever precision you set.
How do I convert torr back to nanopascal?
Use the reverse factor: 1 torr equals 133,322,368,400 nanopascals. You can also use the swap control in the converter above to flip the direction instantly.
What is a nanopascal?
Nanopascal (nPa) is a unit of pressure.
What is a torr?
Torr (Torr) is a unit of pressure.
Is the nanopascal to torr conversion exact?
Yes. Both nanopascal and torr are defined by fixed standards rather than physical artifacts, so the factor of 7.500617e-12 used above is exact to as many digits as you choose to display.
