About Converting Technical atmospheres to Torrs
Technical atmosphere and Torr 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: 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
35 at × 735.5592401 = 25,744.5734 Torr
35 technical atmospheres = 25,744.5734 torrs.
