About Converting Technical atmospheres to Gigapascals
Technical atmosphere and Gigapascal 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 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
100 at × 0.0000980665 = 0.00980665 GPa
100 technical atmospheres = 0.00980665 gigapascals.

Frequently asked questions
How many gigapascals are in 1 technical atmosphere?
1 technical atmosphere equals 0.0000980665 gigapascals, using the exact defined conversion factor rather than an estimate.
How do I convert technical atmosphere to gigapascal?
Multiply the technical atmosphere value by 0.0000980665. The converter above does this instantly to whatever precision you set.
How do I convert gigapascal back to technical atmosphere?
Use the reverse factor: 1 gigapascal equals 10,197.16213 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 gigapascal?
Gigapascal (GPa) is a unit of engineering.
Is the technical atmosphere to gigapascal conversion exact?
Yes. Both technical atmosphere and gigapascal are defined by fixed standards rather than physical artifacts, so the factor of 0.0000980665 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.
