How to Convert Barye to Millimeter of Water
- 1 Ba = 0.01019716213 mmH₂O
- 1 mmH₂O = 98.0665 Ba
- Example: convert 15 Ba to mmH₂O: 15 Ba = 15 × 0.01019716213 mmH₂O = 0.1529574319 mmH₂O
Reference conditions. mmH₂O: Conventional water column: ρ = 1000 kg/m³ and gₙ = 9.80665 m/s² (≈ water at 4 °C).
Formula
mmH₂O = Ba × 0.01019716212978
or mmH₂O = Ba ÷ 98.0665
Derivation from SI units:
- 1 Ba = 1 dyn/cm² = 10⁻⁵ N ÷ 10⁻⁴ m² = 0.1 Pa
- 1 mmH₂O = 1000 kg/m³ × 9.80665 m/s² × 0.001 m = 9.80665 Pa
- 1 Ba = 0.1 Pa ÷ 9.80665 Pa per mmH₂O = 0.01019716212978 mmH₂O
Both units are defined exactly, so the factor is exact. Barye definition: barye; Millimeter of Water definition: millimeter of water.
Worked examples
- A reading of 100 Ba converts to 1.019716213 mmH₂O.
100 Ba × 0.01019716213 = 1.019716213 mmH₂O - A value of 10000 Ba is 101.9716213 mmH₂O.
10000 Ba × 0.01019716213 = 101.9716213 mmH₂O

Where it's used
Baryes are used for older physics and acoustics literature, while millimeters of water appear in fan static pressure and duct design in Asia and Europe. Both measure pressure, stress and differential pressure (force per unit area), so the conversion is a fixed factor.

Frequently asked questions
How many millimeters of water are in 1 barye?
1 Ba = 0.01019716213 mmH₂O.
How do I convert baryes to millimeters of water?
Multiply the value in Ba by 0.01019716213, or divide it by 98.0665. For example, 15 Ba × 0.01019716213 = 0.1529574319 mmH₂O.
Is the Ba to mmH₂O 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).
