You can do the reverse unit conversion from zettabar to mm H2O, or enter any two units below:
mm H2O to terapascal
mm H2O to gigapascal
mm H2O to millibar
mm H2O to pascal
mm H2O to millihg
mm H2O to centipascal
mm H2O to inch of water
mm H2O to meter of air
mm H2O to megapascal
mm H2O to centimeter water
The SI prefix "zetta" represents a factor of 1021, or in exponential notation, 1E21.
So 1 zettabar = 1021 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.
