How to Convert Pascal to Standard Atmosphere

1 pascal = 9.86923 × 10-6 standard atmospheres exact

Standard Atmosphere = Pascal × 9.86923 × 10-6

Example: 63 Pa × 9.86923 × 10-6 = 0.00062176 atm

Reverse Conversion

To convert standard atmospheres back to pascals:

  • Remember, 1 standard atmosphere equals 101325 pascals.
  • To convert 0.00062176 atm to Pa, multiply 0.00062176 x 101325, resulting in 63 Pa.

exact This conversion factor is exact by international definition.

63 Pa is also equal to:

  • 0.063 kPa
  • 0.00063 bar
  • 0.0091374 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 63 pascals in standard atmospheres?

63 pascals equals 0.00062176 standard atmospheres. This is calculated by multiplying 63 by the conversion factor 9.86923 × 10⁻⁶.

What does 63 pascals look like in standard atmospheres?
