How to Convert Barye to Bar
- 1 Ba = 0.000001 bar
- 1 bar = 1000000 Ba
- Example: convert 15 Ba to bar: 15 Ba = 15 × 0.000001 bar = 0.000015 bar
Formula
bar = Ba ÷ 1000000
Derivation from SI units:
- 1 Ba = 1 dyn/cm² = 10⁻⁵ N ÷ 10⁻⁴ m² = 0.1 Pa
- 1 bar = 10⁵ Pa (exact, by definition)
- 1 Ba = 0.1 Pa ÷ 100000 Pa per bar = 0.000001 bar
Both units are defined exactly, so the factor is exact. Barye definition: barye; Bar definition: bar.
Worked examples
- A reading of 100 Ba converts to 0.0001 bar.
100 Ba × 0.000001 = 0.0001 bar - A value of 10000 Ba is 0.01 bar.
10000 Ba × 0.000001 = 0.01 bar

Where it's used
Baryes are used for older physics and acoustics literature, while bar appear in compressed air and pneumatics (6–8 bar). Both measure pressure, stress and differential pressure (force per unit area), so the conversion is a fixed factor.

Frequently asked questions
How many bar are in 1 barye?
1 Ba = 0.000001 bar.
How do I convert baryes to bar?
Multiply the value in Ba by 0.000001, or divide it by 1000000. For example, 15 Ba × 0.000001 = 0.000015 bar.
Is the Ba to bar conversion exact?
Yes. Both units are defined exactly, and 1 Ba is exactly 0.000001 bar.
