You can do the reverse unit conversion from gigapascal to mm H2O, or enter any two units below:
mm H2O to petapascal
mm H2O to millibar
mm H2O to yottapascal
mm H2O to centibar
mm H2O to millipascal
mm H2O to newton/square meter
mm H2O to foot of air
mm H2O to petabar
mm H2O to foot of water
mm H2O to hectobar
The SI prefix "giga" represents a factor of 109, or in exponential notation, 1E9.
So 1 gigapascal = 109 pascals.
The definition of a pascal is as follows:
The pascal (symbol Pa) is the SI unit of pressure.It is equivalent to one newton per square metre. The unit is named after Blaise Pascal, the eminent French mathematician, physicist and philosopher.
