bar to inH2O Conversion Table

Assuming a water density of 1000 kg/m³ and gravity of 9.80665 m/s², a low air pressure reading in bar can be changed to inches of water using the following method:

• 1 inH₂O = 249.089 pascals (Pa)
• 1 bar = 100,000 pascals (Pa)
• inH₂O value x 249.089 Pa = bar value x 100,000 Pa
• inH₂O value = bar value x 401.463

Enter a pressure in bar below to convert it to the equivalent pressure in inH₂O 4°C.
