You can do the reverse unit conversion from attopascal to psia, or enter any two units below:
psia to millihg
psia to kilopond/square centimeter
psia to picopascal
psia to foot water
psia to meganewton/square meter
psia to barye
psia to micrometer of mercury
psia to inch of air
psia to megapascal
psia to centimeter 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 "atto" represents a factor of 10-18, or in exponential notation, 1E-18.
So 1 attopascal = 10-18 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.
