How to Convert mm H2O into Bars

08/13/2009 5:48 AM

We have positive pressure air blowers in our machine. According to manufacturer, the pressure of blower should be 300mm H2O. I want to convert that pressure into bars or mbars. Can anyone help me out?

When you dive, water exerts one bar every 15 feet. You could use that as a rule of thumb. 300mm is about one foot. That is 1/15 of a bar or 66mb.

Sure that's not one bar increase every 33.5 feet?

That gives 300mm of water ≈ 0.03 bar (30 mbar).

That's right. Lohdi is confusing 1 ft w.g. with 1 psi.

300 mm w.g. = 30 mbar, near enough for most purposes.

Cheers.........Codey

That is incorrect. Roughly by a factor of 2.

10 m or 10,000 mm or 393.7 inches is equal to 1 bar.

300 mm = .03 bar or 30 mbar.

To be precise, its 29.42 mbar.

10 meters = 1 bar (approximately, very close)

so

300 mm = 0.03 bar (for all practical purpose)

Atmospheric pressure is approx. 10.2m of water, so you can go from there.

Dear Mr.Signode,

I bar = 1000 mbar = 0.9838 Kg/cm^2 = 10.197 Metres of Water Column = 10197 MM of Water Column

This is based on 1 atmospheric Pressure = 14.696 psi = 1.03 Kg/cm^2 = 1.0469 bar = 34 Feet of Water column. You can easily convert from one unit to other unit.
