You can do the reverse unit conversion from gigapascal to psia, or enter any two units below:
psia to ounce/square inch
psia to inch water column
psia to picobar
psia to attobar
psia to poundal/square foot
psia to gigabar
psia to microbar
psia to kilogram-force/square millimeter
psia to kilogram/square centimeter
psia to inch of mercury
Pounds per square inch absolute (psia) is used to make it clear that the pressure is relative to a vacuum rather than the ambient atmospheric pressure. Since atmospheric pressure at sea level is around 14.7 psi, this will be added to any pressure reading made in air at sea level.
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.
