About Converting Torrs to Micropascals
Torr and Micropascal 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 micropascal is 0.000001 pascal units.
Formula
micropascals = torrs × 133322368.421
This factor comes from each unit's defined relationship to the category's base unit: 1 torr equals 133.322368421 base units, and 1 micropascal equals 0.000001 base units, so dividing one by the other gives the direct torr-to-micropascal factor of 133322368.421.
Simple example
1 Torr × 133322368.4 = 133,322,368.4 uPa
1 torr = 133,322,368.4 micropascals.
Real-world example
35 Torr × 133322368.4 = 4,666,282,895 uPa
35 torrs = 4,666,282,895 micropascals.

Reverse conversion: Micropascal to Torr
1 uPa × 7.500617e-9 = 7.500617e-9 Torr
1 micropascal = 7.500617e-9 torrs.
torrs = micropascals × 7.500617e-9

Frequently asked questions
How many micropascals are in 1 torr?
1 torr equals 133,322,368.4 micropascals, using the exact defined conversion factor rather than an estimate.
How do I convert torr to micropascal?
Multiply the torr value by 133322368.4. The converter above does this instantly to whatever precision you set.
How do I convert micropascal back to torr?
Use the reverse factor: 1 micropascal equals 7.500617e-9 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 micropascal?
Micropascal (uPa) is a unit of pressure.
Is the torr to micropascal conversion exact?
Yes. Both torr and micropascal are defined by fixed standards rather than physical artifacts, so the factor of 133322368.4 used above is exact to as many digits as you choose to display.
