How to Convert Barye to Millibar
- 1 Ba = 0.001 mbar
- 1 mbar = 1000 Ba
- Example: convert 15 Ba to mbar: 15 Ba = 15 × 0.001 mbar = 0.015 mbar
Formula
mbar = Ba ÷ 1000
Derivation from SI units:
- 1 Ba = 1 dyn/cm² = 10⁻⁵ N ÷ 10⁻⁴ m² = 0.1 Pa
- 1 mbar = 10⁻³ bar = 100 Pa = 1 hPa
- 1 Ba = 0.1 Pa ÷ 100 Pa per mbar = 0.001 mbar
Both units are defined exactly, so the factor is exact. Barye definition: barye; Millibar definition: millibar.
Worked examples
- A reading of 100 Ba converts to 0.1 mbar.
100 Ba × 0.001 = 0.1 mbar - A value of 10000 Ba is 10 mbar.
10000 Ba × 0.001 = 10 mbar

Where it's used
Baryes are used for older physics and acoustics literature, while millibars appear in weather maps and barometers (sea level ≈ 1013 mbar). Both measure pressure, stress and differential pressure (force per unit area), so the conversion is a fixed factor.

Frequently asked questions
How many millibars are in 1 barye?
1 Ba = 0.001 mbar.
How do I convert baryes to millibars?
Multiply the value in Ba by 0.001, or divide it by 1000. For example, 15 Ba × 0.001 = 0.015 mbar.
Is the Ba to mbar conversion exact?
Yes. Both units are defined exactly, and 1 Ba is exactly 0.001 mbar.
