Frequently asked questions
What is the source unit in this conversion?
The source unit is the psi (psi). Pounds per square inch.
What is the destination unit in this conversion?
The destination unit is the technical atmosphere (at). Technical atmosphere is kilogram-force per square centimeter.
How do I convert psi to technical atmosphere?
Multiply the psi value by 0.070307. For example, 10 psi × 0.070307 = 0.70307 at.
Is the psi to technical atmosphere conversion exact?
Yes. Both units are defined as fixed multiples of the pascal, the SI-derived unit of pressure, so the conversion factor follows directly from those exact definitions rather than a measured approximation.
Where is this conversion commonly used?
It's used whenever a value expressed in psi needs to be compared with, or reported in, technical atmosphere, such as in engineering specifications, weather readings, tire pressure, or industrial and scientific work.
Can I convert technical atmosphere back to psi?
Yes. Multiply the technical atmosphere value by 14.223343 to get psi.

About this conversion
This page converts psi (psi) to technical atmosphere (at) within the pressure converter.
Pounds per square inch. Technical atmosphere is kilogram-force per square centimeter.
The formula is technical atmosphere = psi × 0.070307, based on each unit's fixed relationship to the pascal, the pressure converter's base unit.
The conversion is exact, since both units are tied to the pascal by a fixed numerical ratio rather than a measured or approximate value.
