How to Convert Bar to Pascal

1 bar = 100000 pascals exact

Pascal = Bar × 100000

Example: 0.129 bar × 100000 = 12900 Pa

Reverse Conversion

To convert pascals back to bar:

  • Remember, 1 pascal equals 1 × 10-5 bar.
  • To convert 12900 Pa to bar, multiply 12900 x 1 × 10-5, resulting in 0.129 bar.

exact This conversion factor is exact by international definition.

0.129 bar is also equal to:

  • 12.9 kPa
  • 1.871 psi
About these units

Bar: Metric pressure unit equal to exactly 100,000 pascals.

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