How to Convert Pascal to Bar

1 pascal = 1 × 10-5 bar exact

Bar = Pascal × 1 × 10-5

Example: 64.5 Pa × 1 × 10-5 = 0.000645 bar

Reverse Conversion

To convert bar back to pascals:

  • Remember, 1 bar equals 100000 pascals.
  • To convert 0.000645 bar to Pa, multiply 0.000645 x 100000, resulting in 64.5 Pa.

exact This conversion factor is exact by international definition.

64.5 Pa is also equal to:

  • 0.0645 kPa
  • 0.0093549 psi
About these units

Pascal: SI derived unit of pressure equal to one newton per square meter (N/m²).

Bar: Metric pressure unit equal to exactly 100,000 pascals.
