About Converting Technical atmospheres to Femtopascals
Technical atmosphere and Femtopascal 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 femtopascal is 1e-15 pascal units.
Formula
femtopascals = technical atmospheres × 9.80665e+19
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 femtopascal equals 1e-15 base units, so dividing one by the other gives the direct technical atmosphere-to-femtopascal factor of 9.80665e+19.
Simple example
1 at × 9.80665e+19 = 9.80665e+19 fPa
1 technical atmosphere = 9.80665e+19 femtopascals.
Real-world example
35 at × 9.80665e+19 = 3.432327e+21 fPa
35 technical atmospheres = 3.432327e+21 femtopascals.
