How to Convert Pascal to Bar

1 pascal = 1 × 10-5 bar exact

Bar = Pascal × 1 × 10-5

Example: 255.5 Pa × 1 × 10-5 = 0.002555 bar

Reverse Conversion

To convert bar back to pascals:

  • Remember, 1 bar equals 100000 pascals.
  • To convert 0.002555 bar to Pa, multiply 0.002555 x 100000, resulting in 255.5 Pa.

exact This conversion factor is exact by international definition.
