Did you know? Outer space (LEO) is 0.001 kPa.

Low Earth orbit has virtually no pressure — about 10-7 Pa, which is considered a hard vacuum.

How to Convert Pascal to Psi

1 pascal = 0.000145038 psi

Psi = Pascal × 0.000145038

Example: 1 Pa × 0.000145038 = 0.00014504 psi

Reverse Conversion

To convert psi back to pascals:

  • Remember, 1 psi equals 6894.76 pascals.
  • To convert 0.00014504 psi to Pa, multiply 0.00014504 x 6894.76, resulting in 1 Pa.

1 Pa is also equal to:

  • 0.001 kPa
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.

Frequently Asked Questions

How much is 1 pascal in psi?

1 pascal equals 0.00014504 psi. This is calculated by multiplying 1 by the conversion factor 0.000145038.

What does 1 pascal look like in psi?

1 pascal (0.00014504 psi) is very low pressure — a gentle breeze creates about 1-10 Pa.

How do you calculate 1 pascal to psi?

Multiply 1 by the conversion factor 0.000145038. The calculation is 1 × 0.000145038 = 0.00014504 psi. This factor is defined by international measurement standards.
