About Converting KSI to Technical atmospheres
KSI and Technical atmosphere 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: Kips per square inch, and technical atmosphere is kilogram-force per square centimeter.
Formula
technical atmospheres = ksi × 70.3069579639
This factor comes from each unit's defined relationship to the category's base unit: 1 ksi equals 6894757.29317 base units, and 1 technical atmosphere equals 98066.5 base units, so dividing one by the other gives the direct ksi-to-technical atmosphere factor of 70.3069579639.
Simple example
1 ksi × 70.30695796 = 70.30695796 at
1 ksi = 70.30695796 technical atmospheres.
Real-world example
100 ksi × 70.30695796 = 7,030.695796 at
100 ksi = 7,030.695796 technical atmospheres.

Frequently asked questions
How many technical atmospheres are in 1 ksi?
1 ksi equals 70.30695796 technical atmospheres, using the exact defined conversion factor rather than an estimate.
How do I convert ksi to technical atmosphere?
Multiply the ksi value by 70.30695796. The converter above does this instantly to whatever precision you set.
How do I convert technical atmosphere back to ksi?
Use the reverse factor: 1 technical atmosphere equals 0.0142233433 ksi. You can also use the swap control in the converter above to flip the direction instantly.
What is a ksi?
KSI (ksi) is a unit of engineering.
What is a technical atmosphere?
Technical atmosphere (at) is a unit of engineering.
Is the ksi to technical atmosphere conversion exact?
Yes. Both ksi and technical atmosphere are defined by fixed standards rather than physical artifacts, so the factor of 70.30695796 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.
