How to Convert Pascal to Bar

1 pascal = 1 × 10-5 bar exact

Bar = Pascal × 1 × 10-5

Example: 21570 Pa × 1 × 10-5 = 0.2157 bar

Reverse Conversion

To convert bar back to pascals:

  • Remember, 1 bar equals 100000 pascals.
  • To convert 0.2157 bar to Pa, multiply 0.2157 x 100000, resulting in 21570 Pa.

exact This conversion factor is exact by international definition.

21570 Pa is also equal to:

  • 21.57 kPa
  • 3.1285 psi
