About Converting Technical atmospheres to Gigapascals
Technical atmosphere and Gigapascal 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 gigapascal is 1000000000 pascal units.
Formula
gigapascals = technical atmospheres × 0.0000980665
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 gigapascal equals 1000000000 base units, so dividing one by the other gives the direct technical atmosphere-to-gigapascal factor of 0.0000980665.
Simple example
1 at × 0.0000980665 = 0.0000980665 GPa
1 technical atmosphere = 0.0000980665 gigapascals.
Real-world example
35 at × 0.0000980665 = 0.0034323275 GPa
35 technical atmospheres = 0.0034323275 gigapascals.
