About Converting Torrs to KSI
Torr and KSI 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 kips per square inch.
Formula
ksi = torrs × 0.0000193367747046
This factor comes from each unit's defined relationship to the category's base unit: 1 torr equals 133.322368421 base units, and 1 ksi equals 6894757.29317 base units, so dividing one by the other gives the direct torr-to-ksi factor of 0.0000193367747046.
Simple example
1 Torr × 0.0000193367747 = 0.0000193368 ksi
1 torr = 0.0000193368 ksi.
Real-world example
100 Torr × 0.0000193367747 = 0.0019336775 ksi
100 torrs = 0.0019336775 ksi.

Reverse conversion: KSI to Torr
0.0000193368 ksi × 51714.93257 = 1.000001308 Torr
0.0000193368 ksi = 1.000001308 torrs.
torrs = ksi × 51714.9325715

Frequently asked questions
How many ksi are in 1 torr?
1 torr equals 0.0000193368 ksi, using the exact defined conversion factor rather than an estimate.
How do I convert torr to ksi?
Multiply the torr value by 0.0000193367747. The converter above does this instantly to whatever precision you set.
How do I convert ksi back to torr?
Use the reverse factor: 1 ksi equals 51,714.93257 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 ksi?
KSI (ksi) is a unit of engineering.
Is the torr to ksi conversion exact?
Yes. Both torr and ksi are defined by fixed standards rather than physical artifacts, so the factor of 0.0000193367747 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.
