## Convert bar to pound/square inch

 bar psi

The above form works if you are measuring differential pressure, such as the difference in psi between two points. It also gives the correct answer for absolute pressure, assuming you are measuring psia, which is the pressure relative to absolute zero vacuum.

If you are measuring relative to vacuum and want to resolve the pressure relative to the atmosphere, then you should use the form below.

bar (relative to vacuum)
psi (relative to atmosphere)

How many bar in 1 psi? The answer is 0.0689475728. We assume you are converting between bar and pound/square inch. You can view more details on each measurement unit: bar or psi The SI derived unit for pressure is the pascal. 1 pascal is equal to 1.0E-5 bar, or 0.00014503773800722 psi. Note that rounding errors may occur, so always check the results. Use this page to learn how to convert between bars and pounds/square inch.

## Definition: Bar

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.

## Definition: Pound/square inch

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.
