How to Convert Barye to Inch of Water
- 1 Ba = 0.000401463076 inH₂O
- 1 inH₂O = 2490.8891 Ba
- Example: convert 15 Ba to inH₂O: 15 Ba = 15 × 0.000401463076 inH₂O = 0.00602194614 inH₂O
Reference conditions. inH₂O: Conventional water column: ρ = 1000 kg/m³ and gₙ = 9.80665 m/s² (≈ water at 4 °C).
Formula
inH₂O = Ba × 0.0004014630759756
or inH₂O = Ba ÷ 2490.8891
Derivation from SI units:
- 1 Ba = 1 dyn/cm² = 10⁻⁵ N ÷ 10⁻⁴ m² = 0.1 Pa
- 1 inH₂O = 1000 kg/m³ × 9.80665 m/s² × 0.0254 m = 249.08891 Pa
- 1 Ba = 0.1 Pa ÷ 249.08891 Pa per inH₂O = 0.0004014630759756 inH₂O
Both units are defined exactly, so the factor is exact. Barye definition: barye; Inch of Water definition: inch of water.
Worked examples
- A reading of 100 Ba converts to 0.0401463076 inH₂O.
100 Ba × 0.000401463076 = 0.0401463076 inH₂O - A value of 10000 Ba is 4.01463076 inH₂O.
10000 Ba × 0.000401463076 = 4.01463076 inH₂O

Where it's used
Baryes are used for older physics and acoustics literature, while inches of water appear in HVAC total external static pressure (residential ≈ 0.5 inH₂O). Both measure pressure, stress and differential pressure (force per unit area), so the conversion is a fixed factor.

Frequently asked questions
How many inches of water are in 1 barye?
1 Ba = 0.000401463076 inH₂O.
How do I convert baryes to inches of water?
Multiply the value in Ba by 0.000401463076, or divide it by 2490.8891. For example, 15 Ba × 0.000401463076 = 0.00602194614 inH₂O.
Is the Ba to inH₂O 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).
