About Converting Technical atmospheres to Megapascals
Technical atmosphere and Megapascal 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 megapascal is 1000000 pascal units.
Formula
megapascals = technical atmospheres × 0.0980665
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 megapascal equals 1000000 base units, so dividing one by the other gives the direct technical atmosphere-to-megapascal factor of 0.0980665.
Simple example
1 at × 0.0980665 = 0.0980665 MPa
1 technical atmosphere = 0.0980665 megapascals.
Real-world example
100 at × 0.0980665 = 9.80665 MPa
100 technical atmospheres = 9.80665 megapascals.

Frequently asked questions
How many megapascals are in 1 technical atmosphere?
1 technical atmosphere equals 0.0980665 megapascals, using the exact defined conversion factor rather than an estimate.
How do I convert technical atmosphere to megapascal?
Multiply the technical atmosphere value by 0.0980665. The converter above does this instantly to whatever precision you set.
How do I convert megapascal back to technical atmosphere?
Use the reverse factor: 1 megapascal equals 10.19716213 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 megapascal?
Megapascal (MPa) is a unit of engineering.
Is the technical atmosphere to megapascal conversion exact?
Yes. Both technical atmosphere and megapascal are defined by fixed standards rather than physical artifacts, so the factor of 0.0980665 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.
