How to Convert Pascal to Bar
- 1 Pa = 0.00001 bar
- 1 bar = 100000 Pa
- Example: convert 15 Pa to bar: 15 Pa = 15 × 0.00001 bar = 0.00015 bar
Formula
bar = Pa ÷ 100000
Derivation from SI units:
- 1 Pa = 1 N/m² = 1 kg·m⁻¹·s⁻²
- 1 bar = 10⁵ Pa (exact, by definition)
Both units are defined exactly, so the factor is exact. Pascal definition: pascal; Bar definition: bar.
Worked examples
- 100000 Pa is exactly 1 bar, which is why the bar is a convenient metric unit.
100000 Pa × 0.00001 = 1 bar - A 500 Pa drop across a cartridge filter element is just 0.005 bar.
500 Pa × 0.00001 = 0.005 bar

Where it's used
Process and hydraulic equipment in Europe is rated in bar, while calculations and lab instruments use pascals. Small differentials in bar give long strings of zeros, so they are normally quoted in mbar or Pa.

Frequently asked questions
How many pascals are in a bar?
Exactly 100 000 Pa (10⁵ Pa) by definition, so 1 Pa = 0.00001 bar.
How many bar are in 1 pascal?
1 Pa = 0.00001 bar.
How do I convert pascals to bar?
Multiply the value in Pa by 0.00001, or divide it by 100000. For example, 15 Pa × 0.00001 = 0.00015 bar.
Is the Pa to bar conversion exact?
Yes. Both units are defined exactly, and 1 Pa is exactly 0.00001 bar.
