Did you know? Outer space (LEO) is 0.001 kPa.

Low Earth orbit has virtually no pressure — about 10-7 Pa, which is considered a hard vacuum.

How to Convert Pascal to Bar

1 pascal = 1 × 10-5 bar exact

Bar = Pascal × 1 × 10-5

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

Reverse Conversion

To convert bar back to pascals:

  • Remember, 1 bar equals 100000 pascals.
  • To convert 1 × 10-5 bar to Pa, multiply 1 × 10-5 x 100000, resulting in 1 Pa.

exact This conversion factor is exact by international definition.

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 1 pascal in bar?

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

What does 1 pascal look like in bar?

1 pascal (1 × 10⁻⁵ bar) is very low pressure — a gentle breeze creates about 1-10 Pa.

How do you calculate 1 pascal to bar?

Multiply 1 by the conversion factor 1 × 10⁻⁵. The calculation is 1 × 1 × 10⁻⁵ = 1 × 10⁻⁵ bar. This factor is defined by international measurement standards.
