About Converting KSI to Torrs
KSI and Torr 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: Kips per square inch, and a torr is 1/760 standard atmosphere.
Formula
torrs = ksi × 51714.9325715
This factor comes from each unit's defined relationship to the category's base unit: 1 ksi equals 6894757.29317 base units, and 1 torr equals 133.322368421 base units, so dividing one by the other gives the direct ksi-to-torr factor of 51714.9325715.
Simple example
1 ksi × 51714.93257 = 51,714.93257 Torr
1 ksi = 51,714.93257 torrs.
Real-world example
100 ksi × 51714.93257 = 5,171,493.257 Torr
100 ksi = 5,171,493.257 torrs.

Frequently asked questions
How many torrs are in 1 ksi?
1 ksi equals 51,714.93257 torrs, using the exact defined conversion factor rather than an estimate.
How do I convert ksi to torr?
Multiply the ksi value by 51714.93257. The converter above does this instantly to whatever precision you set.
How do I convert torr back to ksi?
Use the reverse factor: 1 torr equals 0.0000193368 ksi. You can also use the swap control in the converter above to flip the direction instantly.
What is a ksi?
KSI (ksi) is a unit of engineering.
What is a torr?
Torr (Torr) is a unit of engineering.
Is the ksi to torr conversion exact?
Yes. Both ksi and torr are defined by fixed standards rather than physical artifacts, so the factor of 51714.93257 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.
