How to Convert Pascal to Bar

1 pascal = 1 × 10-5 bar exact

Bar = Pascal × 1 × 10-5

Example: 456 Pa × 1 × 10-5 = 0.00456 bar

Reverse Conversion

To convert bar back to pascals:

  • Remember, 1 bar equals 100000 pascals.
  • To convert 0.00456 bar to Pa, multiply 0.00456 x 100000, resulting in 456 Pa.

exact This conversion factor is exact by international definition.

456 Pa is also equal to:

  • 0.456 kPa
  • 0.066137 psi
