About Converting Pascals to Technical atmospheres
Pascal and Technical atmosphere 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. Pascal is most often used for scientific and engineering pressure measurement worldwide.
Formula
technical atmospheres = pascals × 0.0000101971621298
This factor comes from each unit's defined relationship to the category's base unit: 1 pascal equals 1 base unit, and 1 technical atmosphere equals 98066.5 base units, so dividing one by the other gives the direct pascal-to-technical atmosphere factor of 0.0000101971621298.
Simple example
1 Pa × 0.00001019716213 = 0.0000101972 at
1 pascal = 0.0000101972 technical atmospheres.
Real-world example
35 Pa × 0.00001019716213 = 0.0003569007 at
35 pascals = 0.0003569007 technical atmospheres.

Understanding the Pascal
Pascal (Pa) measures pressure. The pascal is the SI derived unit of pressure: one newton of force per square meter. It is classified as a SI derived unit.
Where it's used: Standard scientific pressure unit worldwide
Uses of the Pascal today
- Scientific and engineering pressure measurement worldwide
- Meteorology (often as hectopascals, equivalent to millibars)
- Material science (stress and strength, typically in megapascals)
History of the Pascal
The pascal is named after Blaise Pascal, whose 17th-century experiments clarified the physics of fluid pressure and vacuum. It was adopted as the SI derived unit of pressure in 1971, replacing the older, non-coherent CGS pressure units used in much scientific work up to that point.
Historical origin. Pascal was not the invention of a single named person; it developed through the process described above.
Understanding the Technical atmosphere (at)
Technical atmosphere is kilogram-force per square centimeter.

Frequently asked questions
How many technical atmospheres are in 1 pascal?
1 pascal equals 0.0000101972 technical atmospheres, using the exact defined conversion factor rather than an estimate.
How do I convert pascal to technical atmosphere?
Multiply the pascal value by 0.00001019716213. The converter above does this instantly to whatever precision you set.
How do I convert technical atmosphere back to pascal?
Use the reverse factor: 1 technical atmosphere equals 98,066.5 pascals. You can also use the swap control in the converter above to flip the direction instantly.
What is a pascal?
Pascal (Pa) measures pressure. The pascal is the SI derived unit of pressure: one newton of force per square meter. It is classified as a SI derived unit.
What is a technical atmosphere?
Technical atmosphere (at) is a unit of pressure.
Is the pascal to technical atmosphere conversion exact?
Yes. Both pascal and technical atmosphere are defined by fixed standards rather than physical artifacts, so the factor of 0.00001019716213 used above is exact to as many digits as you choose to display.
Where is the pascal still used today?
Standard scientific pressure unit worldwide
