How to Convert Pascal to Bar

1 pascal = 1 × 10-5 bar exact

Bar = Pascal × 1 × 10-5

Example: 556 Pa × 1 × 10-5 = 0.00556 bar

Reverse Conversion

To convert bar back to pascals:

  • Remember, 1 bar equals 100000 pascals.
  • To convert 0.00556 bar to Pa, multiply 0.00556 x 100000, resulting in 556 Pa.

exact This conversion factor is exact by international definition.

556 Pa is also equal to:

  • 0.556 kPa
  • 0.080641 psi
About these units
