How to Convert Pascal to Bar

1 pascal = 1 × 10-5 bar exact

Bar = Pascal × 1 × 10-5

Example: 661.1 Pa × 1 × 10-5 = 0.006611 bar

Reverse Conversion

To convert bar back to pascals:

  • Remember, 1 bar equals 100000 pascals.
  • To convert 0.006611 bar to Pa, multiply 0.006611 x 100000, resulting in 661.1 Pa.

exact This conversion factor is exact by international definition.

661.1 Pa is also equal to:

  • 0.6611 kPa
  • 0.095884 psi
