How to Convert Psi to Technical Atmosphere

1 psi = 0.070307 technical atmospheres

Technical Atmosphere = Psi × 0.070307

Example: 100 psi × 0.070307 = 7.0307 at

Reverse Conversion

To convert technical atmospheres back to psi:

  • Remember, 1 technical atmosphere equals 14.2233 psi.
  • To convert 7.0307 at to psi, multiply 7.0307 x 14.2233, resulting in 100 psi.
