How to Convert Atmosphere to Barye
- 1 atm = 1013250 Ba
- 1 Ba = 9.869232667 × 10⁻⁷ atm
- Example: convert 15 atm to Ba: 15 atm = 15 × 1013250 Ba = 15198750 Ba
Formula
Ba = atm × 1013250
Derivation from SI units:
- 1 atm = 101 325 Pa (exact, by definition)
- 1 Ba = 1 dyn/cm² = 10⁻⁵ N ÷ 10⁻⁴ m² = 0.1 Pa
- 1 atm = 101325 Pa ÷ 0.1 Pa per Ba = 1013250 Ba
Both units are defined exactly, so the factor is exact. Atmosphere definition: atmosphere; Barye definition: barye.
Worked examples
- A reading of 1.5 atm converts to 1519875 Ba.
1.5 atm × 1013250 = 1519875 Ba - A value of 10 atm is 10132500 Ba.
10 atm × 1013250 = 10132500 Ba

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