How to Convert Barye to Atmosphere
- 1 Ba = 9.869232667 × 10⁻⁷ atm
- 1 atm = 1013250 Ba
- Example: convert 15 Ba to atm: 15 Ba = 15 × 9.869232667 × 10⁻⁷ atm = 0.000014803849 atm
Formula
atm = Ba ÷ 1013250
Derivation from SI units:
- 1 Ba = 1 dyn/cm² = 10⁻⁵ N ÷ 10⁻⁴ m² = 0.1 Pa
- 1 atm = 101 325 Pa (exact, by definition)
- 1 Ba = 0.1 Pa ÷ 101325 Pa per atm = 9.86923266716 × 10⁻⁷ atm
Both units are defined exactly, so the factor is exact. Barye definition: barye; Atmosphere definition: atmosphere.
Worked examples
- A reading of 100 Ba converts to 0.00009869232667 atm.
100 Ba × 9.869232667 × 10⁻⁷ = 0.00009869232667 atm - A value of 10000 Ba is 0.009869232667 atm.
10000 Ba × 9.869232667 × 10⁻⁷ = 0.009869232667 atm

Where it's used
Baryes are used for older physics and acoustics literature, while atmospheres appear in chemistry and gas laws (STP and NTP conditions). Both measure pressure, stress and differential pressure (force per unit area), so the conversion is a fixed factor.

Frequently asked questions
How many atmospheres are in 1 barye?
1 Ba = 9.869232667 × 10⁻⁷ atm.
How do I convert baryes to atmospheres?
Multiply the value in Ba by 9.869232667 × 10⁻⁷, or divide it by 1013250. For example, 15 Ba × 9.869232667 × 10⁻⁷ = 0.000014803849 atm.
Is the Ba to atm conversion exact?
Yes. Both units are defined exactly, so the ratio is exact; its decimal form does not terminate and is shown here to 10 significant figures (more with the precision selector).
