About Converting Technical atmospheres to KSI
Technical atmosphere and KSI 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 kips per square inch.
Formula
ksi = technical atmospheres × 0.0142233433071
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 ksi equals 6894757.29317 base units, so dividing one by the other gives the direct technical atmosphere-to-ksi factor of 0.0142233433071.
Simple example
1 at × 0.01422334331 = 0.0142233433 ksi
1 technical atmosphere = 0.0142233433 ksi.
Real-world example
35 at × 0.01422334331 = 0.4978170157 ksi
35 technical atmospheres = 0.4978170157 ksi.
