How to Convert Pascal to Standard Atmosphere

1 pascal = 9.86923 × 10-6 standard atmospheres exact

Standard Atmosphere = Pascal × 9.86923 × 10-6

Example: 15 Pa × 9.86923 × 10-6 = 0.00014804 atm

Reverse Conversion

To convert standard atmospheres back to pascals:

  • Remember, 1 standard atmosphere equals 101325 pascals.
  • To convert 0.00014804 atm to Pa, multiply 0.00014804 x 101325, resulting in 15 Pa.

exact This conversion factor is exact by international definition.

15 Pa is also equal to:

  • 0.015 kPa
  • 0.00015 bar
  • 0.0021756 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

How much is 15 pascals in standard atmospheres?

15 pascals equals 0.00014804 standard atmospheres. This is calculated by multiplying 15 by the conversion factor 9.86923 × 10⁻⁶.

What does 15 pascals look like in standard atmospheres?

15 pascals (0.00014804 standard atmospheres) is very low pressure — a gentle breeze creates about 1-10 Pa.

How do you calculate 15 pascals to standard atmospheres?

Multiply 15 by the conversion factor 9.86923 × 10⁻⁶. The calculation is 15 × 9.86923 × 10⁻⁶ = 0.00014804 standard atmospheres. This factor is defined by international measurement standards.
