4.2 psi (28.9 kPa) is comparable to the thin air at extreme altitude, like the summit of Mount Everest.

Did you know? Mount Everest summit is 33.7 kPa.

At 8,849 m altitude, air pressure drops to ~33.7 kPa (4.89 psi) — about 1/3 of sea level.

How to Convert Pascal to Bar

1 pascal = 1 × 10-5 bar exact

Bar = Pascal × 1 × 10-5

Example: 28900 Pa × 1 × 10-5 = 0.289 bar

Reverse Conversion

To convert bar back to pascals:

  • Remember, 1 bar equals 100000 pascals.
  • To convert 0.289 bar to Pa, multiply 0.289 x 100000, resulting in 28900 Pa.

exact This conversion factor is exact by international definition.

28900 Pa is also equal to:

  • 28.9 kPa
  • 4.1916 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
