How to Convert Bar to Pascal

1 bar = 100000 pascals exact

Pascal = Bar × 100000

Example: 0.258 bar × 100000 = 25800 Pa

Reverse Conversion

To convert pascals back to bar:

  • Remember, 1 pascal equals 1 × 10-5 bar.
  • To convert 25800 Pa to bar, multiply 25800 x 1 × 10-5, resulting in 0.258 bar.

exact This conversion factor is exact by international definition.

0.258 bar is also equal to:

  • 25.8 kPa
  • 3.742 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).
