A stored-pressure fire extinguisher operates at about 1,200 kPa (175 psi).

How to Convert Technical Atmosphere to Psi

1 technical atmosphere = 14.2233 psi

Psi = Technical Atmosphere × 14.2233

Example: 12 at × 14.2233 = 170.68 psi

Reverse Conversion

To convert psi back to technical atmospheres:

  • Remember, 1 psi equals 0.070307 technical atmospheres.
  • To convert 170.68 psi to at, multiply 170.68 x 0.070307, resulting in 12 at.

12 at is also equal to:

  • 1176800 pascal
  • 1176.8 kPa
  • 11.768 bar
