How to Convert Pascal to Bar

1 pascal = 1 × 10-5 bar exact

Bar = Pascal × 1 × 10-5

Example: 686 Pa × 1 × 10-5 = 0.00686 bar

Reverse Conversion

To convert bar back to pascals:

  • Remember, 1 bar equals 100000 pascals.
  • To convert 0.00686 bar to Pa, multiply 0.00686 x 100000, resulting in 686 Pa.

exact This conversion factor is exact by international definition.

686 Pa is also equal to:

  • 0.686 kPa
  • 0.099496 psi
