You can do the reverse unit conversion from petabar to mm H2O, or enter any two units below:
mm H2O to megapascal
mm H2O to terapascal
mm H2O to millimeter of water
mm H2O to inch mercury
mm H2O to terabar
mm H2O to picopascal
mm H2O to atmosphere
mm H2O to dyne/square centimeter
mm H2O to dekapascal
mm H2O to kilonewton/square meter
The SI prefix "peta" represents a factor of 1015, or in exponential notation, 1E15.
So 1 petabar = 1015 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.
