How to Convert Pascal to Psi

1 pascal = 0.000145038 psi

Psi = Pascal × 0.000145038

Example: 690 Pa × 0.000145038 = 0.10008 psi

Reverse Conversion

To convert psi back to pascals:

  • Remember, 1 psi equals 6894.76 pascals.
  • To convert 0.10008 psi to Pa, multiply 0.10008 x 6894.76, resulting in 690 Pa.

690 Pa is also equal to:

  • 0.69 kPa
  • 0.0069 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.
