About Converting Torrs to Technical atmospheres
Torr and Technical atmosphere 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 technical atmosphere is kilogram-force per square centimeter.
Formula
technical atmospheres = torrs × 0.00135950980632
This factor comes from each unit's defined relationship to the category's base unit: 1 torr equals 133.322368421 base units, and 1 technical atmosphere equals 98066.5 base units, so dividing one by the other gives the direct torr-to-technical atmosphere factor of 0.00135950980632.
Simple example
1 Torr × 0.001359509806 = 0.0013595098 at
1 torr = 0.0013595098 technical atmospheres.
Real-world example
100 Torr × 0.001359509806 = 0.1359509806 at
100 torrs = 0.1359509806 technical atmospheres.

Frequently asked questions
How many technical atmospheres are in 1 torr?
1 torr equals 0.0013595098 technical atmospheres, using the exact defined conversion factor rather than an estimate.
How do I convert torr to technical atmosphere?
Multiply the torr value by 0.001359509806. The converter above does this instantly to whatever precision you set.
How do I convert technical atmosphere back to torr?
Use the reverse factor: 1 technical atmosphere equals 735.5592401 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 technical atmosphere?
Technical atmosphere (at) is a unit of engineering.
Is the torr to technical atmosphere conversion exact?
Yes. Both torr and technical atmosphere are defined by fixed standards rather than physical artifacts, so the factor of 0.001359509806 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.
