How to Convert Pascal to Bar

1 pascal = 1 × 10-5 bar exact

Bar = Pascal × 1 × 10-5

Example: 20 Pa × 1 × 10-5 = 0.0002 bar

Reverse Conversion

To convert bar back to pascals:

  • Remember, 1 bar equals 100000 pascals.
  • To convert 0.0002 bar to Pa, multiply 0.0002 x 100000, resulting in 20 Pa.

exact This conversion factor is exact by international definition.
