Did you know? Mount Everest summit is 33.7 kPa.

At 8,849 m altitude, air pressure drops to ~33.7 kPa (4.89 psi) — about 1/3 of sea level.

How to Convert Pascal to Psi

1 pascal = 0.000145038 psi

Psi = Pascal × 0.000145038

Example: 30780 Pa × 0.000145038 = 4.4643 psi

Reverse Conversion

To convert psi back to pascals:

  • Remember, 1 psi equals 6894.76 pascals.
  • To convert 4.4643 psi to Pa, multiply 4.4643 x 6894.76, resulting in 30780 Pa.

30780 Pa is also equal to:

  • 30.78 kPa
  • 0.3078 bar
About these units

Pascal: SI derived unit of pressure equal to one newton per square meter (N/m²).

Psi: Imperial/US customary pressure unit equal to one pound-force per square inch.
