You can do the reverse unit conversion from gigabar to mm H2O, or enter any two units below:
mm H2O to nanopascal
mm H2O to femtobar
mm H2O to nanobar
mm H2O to meganewton/square meter
mm H2O to kilopond/square millimeter
mm H2O to exapascal
mm H2O to kilogram-force/square meter
mm H2O to inch of mercury
mm H2O to ton/square inch
mm H2O to kilopond/square centimeter
The SI prefix "giga" represents a factor of 109, or in exponential notation, 1E9.
So 1 gigabar = 109 bars.
The definition of a bar is as follows:
The bar is a measurement unit of pressure, equal to 1,000,000 dynes per square centimetre (baryes), or 100,000 newtons per square metre (pascals). The word bar is of Greek origin, báros meaning weight. Its official symbol is "bar"; the earlier "b" is now deprecated, but still often seen especially as "mb" rather than the proper "mbar" for millibars.
