How to Convert Pascal to Bar

1 pascal = 1 × 10-5 bar exact

Bar = Pascal × 1 × 10-5

Example: 18 Pa × 1 × 10-5 = 0.00018 bar

Reverse Conversion

To convert bar back to pascals:

  • Remember, 1 bar equals 100000 pascals.
  • To convert 0.00018 bar to Pa, multiply 0.00018 x 100000, resulting in 18 Pa.

exact This conversion factor is exact by international definition.

18 Pa is also equal to:

  • 0.018 kPa
  • 0.0026107 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

How much is 18 pascals in bar?

18 pascals equals 0.00018 bar. This is calculated by multiplying 18 by the conversion factor 1 × 10⁻⁵.

What does 18 pascals look like in bar?

18 pascals (0.00018 bar) is very low pressure — a gentle breeze creates about 1-10 Pa.
