Illustration of standard atmospheric pressure
15.8 psi (109 kPa) is comparable to standard atmospheric pressure at sea level (101.325 kPa).

Did you know? Standard atmosphere (1 atm) is 101.325 kPa.

Sea-level atmospheric pressure is 101.325 kPa = 14.696 psi = 760 mmHg = 1 atm exactly.

How to Convert Pascal to Bar

1 pascal = 1 × 10-5 bar exact

Bar = Pascal × 1 × 10-5

Example: 108900 Pa × 1 × 10-5 = 1.089 bar

Reverse Conversion

To convert bar back to pascals:

  • Remember, 1 bar equals 100000 pascals.
  • To convert 1.089 bar to Pa, multiply 1.089 x 100000, resulting in 108900 Pa.

exact This conversion factor is exact by international definition.

108900 Pa is also equal to:

  • 108.9 kPa
  • 15.795 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.

Frequently Asked Questions
