Bar to meters of water
Type a value in bar to get it in m H₂O instantly.
3,059.149m H₂O
That's 3× as strong as desalination brine — nothing on our list beats it. That would hold up a column of water about 3,059 meters tall.
What it means
How hard does it pull?
Van ’t Hoff’s law is exact only for dilute solutions at 25 °C. Concentrated brines deviate, which is why desalination plants use measured data.
The math
How to convert bar to m H₂O
To convert bar to meters of water, multiply by 10.1972.
Example: 300 bar × 10.1972 = 3,059.15 m H₂O.
In the other direction, 1 m H₂O = 0.0980665 bar.
