About Converting Torrs to Kilopascals
Torr and Kilopascal 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 kilopascal is 1000 pascal units.
Formula
kilopascals = torrs × 0.133322368421
This factor comes from each unit's defined relationship to the category's base unit: 1 torr equals 133.322368421 base units, and 1 kilopascal equals 1000 base units, so dividing one by the other gives the direct torr-to-kilopascal factor of 0.133322368421.
Simple example
1 Torr × 0.1333223684 = 0.1333223684 kPa
1 torr = 0.1333223684 kilopascals.
Real-world example
100 Torr × 0.1333223684 = 13.33223684 kPa
100 torrs = 13.33223684 kilopascals.

Frequently asked questions
How many kilopascals are in 1 torr?
1 torr equals 0.1333223684 kilopascals, using the exact defined conversion factor rather than an estimate.
How do I convert torr to kilopascal?
Multiply the torr value by 0.1333223684. The converter above does this instantly to whatever precision you set.
How do I convert kilopascal back to torr?
Use the reverse factor: 1 kilopascal equals 7.500616827 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 kilopascal?
Kilopascal (kPa) is a unit of engineering.
Is the torr to kilopascal conversion exact?
Yes. Both torr and kilopascal are defined by fixed standards rather than physical artifacts, so the factor of 0.1333223684 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.
