About Converting Technical atmospheres to Petapascals
Technical atmosphere and Petapascal both measure a quantity used in structural or mechanical engineering — commonly stress, pressure, force, torque, power, or energy — where converting between the unit conventions used in different regions, industries, or equipment specifications is a routine part of design work. Specifically: Technical atmosphere is kilogram-force per square centimeter, and petapascal is 1000000000000000 pascal units.
Formula
petapascals = technical atmospheres × 9.80665e-11
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 petapascal equals 1e+15 base units, so dividing one by the other gives the direct technical atmosphere-to-petapascal factor of 9.80665e-11.
Simple example
1 at × 9.80665e-11 = 9.80665e-11 PPa
1 technical atmosphere = 9.80665e-11 petapascals.
Real-world example
100 at × 9.80665e-11 = 9.80665e-9 PPa
100 technical atmospheres = 9.80665e-9 petapascals.

Frequently asked questions
How many petapascals are in 1 technical atmosphere?
1 technical atmosphere equals 9.80665e-11 petapascals, using the exact defined conversion factor rather than an estimate.
How do I convert technical atmosphere to petapascal?
Multiply the technical atmosphere value by 9.80665e-11. The converter above does this instantly to whatever precision you set.
How do I convert petapascal back to technical atmosphere?
Use the reverse factor: 1 petapascal equals 10,197,162,130 technical atmospheres. You can also use the swap control in the converter above to flip the direction instantly.
What is a technical atmosphere?
Technical atmosphere (at) is a unit of engineering.
What is a petapascal?
Petapascal (PPa) is a unit of engineering.
Is the technical atmosphere to petapascal conversion exact?
Yes. Both technical atmosphere and petapascal are defined by fixed standards rather than physical artifacts, so the factor of 9.80665e-11 used above is exact to as many digits as you choose to display.
Why do engineering unit conventions vary so much by region and industry?
Pressure, force, and stress can be expressed in metric (pascal, newton), US customary (psi, pound-force), or older and industry-specific units (atmosphere, torr, kip) depending on the country, industry, and even the equipment manufacturer, which is why engineers routinely need to convert between them when working across specs from different sources.
