How to Convert Pascal to Standard Atmosphere

1 pascal = 9.86923 × 10-6 standard atmospheres exact

Standard Atmosphere = Pascal × 9.86923 × 10-6

Example: 104 Pa × 9.86923 × 10-6 = 0.0010264 atm

Reverse Conversion

To convert standard atmospheres back to pascals:

  • Remember, 1 standard atmosphere equals 101325 pascals.
  • To convert 0.0010264 atm to Pa, multiply 0.0010264 x 101325, resulting in 104 Pa.

exact This conversion factor is exact by international definition.

104 Pa is also equal to:

  • 0.104 kPa
  • 0.00104 bar
  • 0.015084 psi
About these units

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

Standard atmosphere: Standard unit of atmospheric pressure defined as exactly 101,325 pascals.

Frequently Asked Questions
