How to Convert Barye to Centimeter of Water
- 1 Ba = 0.001019716213 cmH₂O
- 1 cmH₂O = 980.665 Ba
- Example: convert 15 Ba to cmH₂O: 15 Ba = 15 × 0.001019716213 cmH₂O = 0.01529574319 cmH₂O
Reference conditions. cmH₂O: Conventional water column: ρ = 1000 kg/m³ and gₙ = 9.80665 m/s² (≈ water at 4 °C).
Formula
cmH₂O = Ba × 0.001019716212978
or cmH₂O = Ba ÷ 980.665
Derivation from SI units:
- 1 Ba = 1 dyn/cm² = 10⁻⁵ N ÷ 10⁻⁴ m² = 0.1 Pa
- 1 cmH₂O = 1000 kg/m³ × 9.80665 m/s² × 0.01 m = 98.0665 Pa
- 1 Ba = 0.1 Pa ÷ 98.0665 Pa per cmH₂O = 0.001019716212978 cmH₂O
Both units are defined exactly, so the factor is exact. Barye definition: barye; Centimeter of Water definition: centimeter of water.
Worked examples
- A reading of 100 Ba converts to 0.1019716213 cmH₂O.
100 Ba × 0.001019716213 = 0.1019716213 cmH₂O - A value of 10000 Ba is 10.19716213 cmH₂O.
10000 Ba × 0.001019716213 = 10.19716213 cmH₂O

Where it's used
Baryes are used for older physics and acoustics literature, while centimeters of water appear in mechanical ventilation (PEEP 5–10 cmH₂O, plateau pressure under 30 cmH₂O). Both measure pressure, stress and differential pressure (force per unit area), so the conversion is a fixed factor.

Frequently asked questions
How many centimeters of water are in 1 barye?
1 Ba = 0.001019716213 cmH₂O.
How do I convert baryes to centimeters of water?
Multiply the value in Ba by 0.001019716213, or divide it by 980.665. For example, 15 Ba × 0.001019716213 = 0.01529574319 cmH₂O.
Is the Ba to cmH₂O 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).
