Frequently asked questions
What is the source unit in this conversion?
The source unit is the technical atmosphere (at). Technical atmosphere is kilogram-force per square centimeter.
What is the destination unit in this conversion?
The destination unit is the psi (psi). Pounds per square inch.
How do I convert technical atmosphere to psi?
Multiply the technical atmosphere value by 14.223343. For example, 10 at × 14.223343 = 142.233433 psi.
Is the technical atmosphere to psi 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 technical atmosphere needs to be compared with, or reported in, psi, such as in engineering specifications, weather readings, tire pressure, or industrial and scientific work.
Can I convert psi back to technical atmosphere?
Yes. Multiply the psi value by 0.070307 to get technical atmosphere.

About this conversion
This page converts technical atmosphere (at) to psi (psi) within the pressure converter.
Technical atmosphere is kilogram-force per square centimeter. Pounds per square inch.
The formula is psi = technical atmosphere × 14.223343, 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.
