About Converting Technical atmospheres to Torrs
Technical atmosphere 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: Technical atmosphere is kilogram-force per square centimeter, and a torr is 1/760 standard atmosphere.
Formula
torrs = technical atmospheres × 735.559240069
This factor comes from each unit's defined relationship to the category's base unit: 1 technical atmosphere equals 98066.5 base units, and 1 torr equals 133.322368421 base units, so dividing one by the other gives the direct technical atmosphere-to-torr factor of 735.559240069.
Simple example
1 at × 735.5592401 = 735.5592401 Torr
1 technical atmosphere = 735.5592401 torrs.
Real-world example
100 at × 735.5592401 = 73,555.92401 Torr
100 technical atmospheres = 73,555.92401 torrs.

Frequently asked questions
How many torrs are in 1 technical atmosphere?
1 technical atmosphere equals 735.5592401 torrs, using the exact defined conversion factor rather than an estimate.
How do I convert technical atmosphere to torr?
Multiply the technical atmosphere value by 735.5592401. The converter above does this instantly to whatever precision you set.
How do I convert torr back to technical atmosphere?
Use the reverse factor: 1 torr equals 0.0013595098 technical atmospheres. You can also use the swap control in the converter above to flip the direction instantly.
What is a technical atmosphere?
Technical atmosphere (at) is a unit of engineering.
What is a torr?
Torr (Torr) is a unit of engineering.
Is the technical atmosphere to torr conversion exact?
Yes. Both technical atmosphere and torr are defined by fixed standards rather than physical artifacts, so the factor of 735.5592401 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.
