How many psi in 1 psia? The answer is 1. We assume you are converting between pound/square inch and pound/square inch [absolute]. You can view more details on each measurement unit: psi or psia The SI derived unit for pressure is the pascal. 1 pascal is equal to 0.00014503773800722 psi, or 0.00014503773800722 psia. Note that rounding errors may occur, so always check the results. Use this page to learn how to convert between pounds/square inch and pounds/square inch. Type in your own numbers in the form to convert the units!
1 psi to psia = 1 psia
5 psi to psia = 5 psia
10 psi to psia = 10 psia
20 psi to psia = 20 psia
30 psi to psia = 30 psia
40 psi to psia = 40 psia
50 psi to psia = 50 psia
75 psi to psia = 75 psia
100 psi to psia = 100 psia
You can do the reverse unit conversion from psia to psi, or enter any two units below:
The pound per square inch or, more accurately, pound-force per square inch (symbol: psi or lbf/in² or lbf/in²) is a unit of pressure or of stress based on avoirdupois units. It is the pressure resulting from a force of one pound-force applied to an area of one square inch.
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.
