How to Convert Bar to Pascal

1 bar = 100000 pascals exact

Pascal = Bar × 100000

Example: 4.991 bar × 100000 = 499100 Pa

Reverse Conversion

To convert pascals back to bar:

  • Remember, 1 pascal equals 1 × 10-5 bar.
  • To convert 499100 Pa to bar, multiply 499100 x 1 × 10-5, resulting in 4.991 bar.

exact This conversion factor is exact by international definition.

4.991 bar is also equal to:

  • 499.1 kPa
  • 72.388 psi
