How to convert Inch of Water to Bar
Multiply the inch of water value by 0.00249089: 1 inH₂O = 0.00249089 bar. Going the other way, 1 bar = 401.463 inH₂O, so divide by 0.00249089 or use the Bar to Inch of Water converter.
About these units
Inch of Water (inH₂O)
An inch of water is the pressure of a column of water 1 inch high, about 249 pascals. It is used for ventilation ducts and low gas pressures.
Bar (bar)
A bar is exactly 100,000 pascals, very close to average atmospheric pressure at sea level. Tyre pressures and scuba tanks are often rated in bar.
