How to Convert Pascal to Standard Atmosphere

1 pascal = 9.86923 × 10-6 standard atmospheres exact

Standard Atmosphere = Pascal × 9.86923 × 10-6

Example: 13 Pa × 9.86923 × 10-6 = 0.0001283 atm

Reverse Conversion

To convert standard atmospheres back to pascals:

  • Remember, 1 standard atmosphere equals 101325 pascals.
  • To convert 0.0001283 atm to Pa, multiply 0.0001283 x 101325, resulting in 13 Pa.

exact This conversion factor is exact by international definition.

13 Pa is also equal to:

  • 0.013 kPa
  • 0.00013 bar
  • 0.0018855 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 13 pascals in standard atmospheres?

13 pascals equals 0.0001283 standard atmospheres. This is calculated by multiplying 13 by the conversion factor 9.86923 × 10⁻⁶.

What does 13 pascals look like in standard atmospheres?

13 pascals (0.0001283 standard atmospheres) is very low pressure — a gentle breeze creates about 1-10 Pa.

How do you calculate 13 pascals to standard atmospheres?

Multiply 13 by the conversion factor 9.86923 × 10⁻⁶. The calculation is 13 × 9.86923 × 10⁻⁶ = 0.0001283 standard atmospheres. This factor is defined by international measurement standards.
