How to Convert Pascal to Bar

1 pascal = 1 × 10-5 bar exact

Bar = Pascal × 1 × 10-5

Example: 178 Pa × 1 × 10-5 = 0.00178 bar

Reverse Conversion

To convert bar back to pascals:

  • Remember, 1 bar equals 100000 pascals.
  • To convert 0.00178 bar to Pa, multiply 0.00178 x 100000, resulting in 178 Pa.

exact This conversion factor is exact by international definition.

178 Pa is also equal to:

  • 0.178 kPa
  • 0.025817 psi
About these units

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