How to convert Hectopascal to Inch of Water
Multiply the hectopascal value by 0.401463: 1 hPa = 0.401463 inH₂O. Going the other way, 1 inH₂O = 2.49089 hPa, so divide by 0.401463 or use the Inch of Water to Hectopascal converter.
About these units
Hectopascal (hPa)
A hectopascal is 100 pascals, identical to a millibar. Weather forecasts report atmospheric pressure in hPa, typically around 1,013.
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.
