Barye (Ba)
The barye (Ba) is the CGS unit of pressure, one dyne per square centimetre, equal to exactly 0.1 Pa.
Symbol: Ba
Quantity: pressure, stress and differential pressure (force per unit area)
SI relation: 1 Ba = 0.1 Pa (exact)
Derivation: 1 Ba = 1 dyn/cm² = 10⁻⁵ N ÷ 10⁻⁴ m² = 0.1 Pa
Exact: yes, by definition
Typical uses
- Older physics and acoustics literature
- CGS-based calculations in astrophysics and fluid mechanics
