How to Convert Psi to Technical Atmosphere

1 psi = 0.070307 technical atmospheres

Technical Atmosphere = Psi × 0.070307

Example: 90 psi × 0.070307 = 6.3276 at

Reverse Conversion

To convert technical atmospheres back to psi:

  • Remember, 1 technical atmosphere equals 14.2233 psi.
  • To convert 6.3276 at to psi, multiply 6.3276 x 14.2233, resulting in 90 psi.
