Convert Decibars to Baryes

Formula

Ba = dbar × 100000

Derivation from SI units:

• 1 dbar = 10⁻¹ bar = 10⁴ Pa
• 1 Ba = 1 dyn/cm² = 10⁻⁵ N ÷ 10⁻⁴ m² = 0.1 Pa
• 1 dbar = 10000 Pa ÷ 0.1 Pa per Ba = 100000 Ba

Both units are defined exactly, so the factor is exact. Decibar definition: decibar; Barye definition: barye.

Worked examples

1. A reading of 50 dbar converts to 5000000 Ba.
   50 dbar × 100000 = 5000000 Ba
2. A value of 1000 dbar is 100000000 Ba.
   1000 dbar × 100000 = 100000000 Ba

Where it's used

Decibars are used for oceanography: CTD instruments report sea pressure in dbar, 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.
