About Converting Torrs to Technical atmospheres
Torr and Technical atmosphere both show up on pressure gauges — psi is standard on US tire and tool specifications, while bar is the everyday pressure unit across most of the rest of the world. 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
35 Torr × 0.001359509806 = 0.0475828432 at
35 torrs = 0.0475828432 technical atmospheres.
