You can do the reverse unit conversion from zeptobar to mm H2O, or enter any two units below:
mm H2O to centimeter of water
mm H2O to millitorr
mm H2O to microbar
mm H2O to yoctobar
mm H2O to micropascal
mm H2O to hectopascal
mm H2O to nanobar
mm H2O to inch water column
mm H2O to centimeter of mercury
mm H2O to kilogram/square centimeter
The SI prefix "zepto" represents a factor of 10-21, or in exponential notation, 1E-21.
So 1 zeptobar = 10-21 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.
