About Converting Technical atmospheres to Millibars
Technical atmosphere and Millibar 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 millibar is 100 pascals.
Formula
millibars = technical atmospheres × 980.665
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 millibar equals 100 base units, so dividing one by the other gives the direct technical atmosphere-to-millibar factor of 980.665.
Simple example
1 at × 980.665 = 980.665 mbar
1 technical atmosphere = 980.665 millibars.
Real-world example
35 at × 980.665 = 34,323.275 mbar
35 technical atmospheres = 34,323.275 millibars.
