![]() Symbols, abbreviations, or full names for units of length,Īrea, mass, pressure, and other types. This calculator allows you to convert from Pascal to Psi and in a reverse direction. It is the pressure resulting from a force of one pound-force applied to an area of one square inch.Ĭonversion calculator for all types of measurement units. 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. The unit, named after Blaise Pascal, is defined as one newton per square metre 1 and is equivalent to 10 barye (Ba) in the CGS system. Thus a reading of 30 psig on a tire gauge represents an absolute pressure of 44.7 psi. The pascal (symbol: Pa) is the unit of pressure in the International System of Units (SI), and is also used to quantify internal pressure, stress, Young's modulus, and ultimate tensile strength. If a pressure gauge is calibrated to read zero in space, then at sea level on Earth it would read 14.7 psi. PSI definition: PSI is a unit of pressure expressed in pounds of force per square inch of area. Humans do not feel this pressure because internal pressure of liquid in their bodies matches the external pressure. The commonly used multiple units of the pascal are the hectopascal (1 hPa 100 Pa), kilopascal ( Pa), and megapascal (1 MPa 1,000,000 Pa). At sea level, Earth's atmosphere actually exerts a pressure of 14.7 psi. By contrast, psia measures pressure relative to a vacuum (such as that in space). Psig (pound-force per square inch gauge) is a unit of pressure relative to the surrounding atmosphere. Psi to psig, or enter any two units below: Enter two units to convert From: We assume you are converting between pound/square inch and pascal.You can view more details on each measurement unit: PSI or pascal The SI derived unit for pressure is the pascal. Symbols, abbreviations, or full names for units of length,Īrea, mass, pressure, and other types.You can do the reverse unit conversion from More information from the unit converter. You can find metric conversion tables for SI units, as wellĪs English units, currency, and other data. The unit is named after Blaise Pascal, the eminent French mathematician, physicist and philosopher.Ĭonversion calculator for all types of measurement units. Task: Convert 85,000 pascals to psi (show work) Formula: Pa ÷ 6,894.75729 psi Calculations: 85,000 Pa ÷ 6,894.75729 12. 1 ksi ksi 6894757.2931783 pascal Pa ksi to pascal, pascal to ksi. 1 psi psi 6894.7572931783 pascal Pa psi to pascal, pascal to psi. 00 pascal Pa bar to pascal, pascal to bar. The pascal (symbol Pa) is the SI unit of pressure.It is equivalent to one newton per square metre. pascal Pa 1 kilopascal kPa 1000 pascal Pa kilopascal to pascal, pascal to kilopascal. Means, 75000 pascals (pa) is equal to 10. ![]() It is the pressure resulting from a force of one pound-force applied to an area of one square inch. So, to convert directly from bar to pounds per square inch, you multiply by 14.503774. Pascal to PSI, or enter any two units below: Enter two units to convert From: For example, to convert from bar to pounds per square inch you would multiply by 100000 then divide by 6894.757. You can do the reverse unit conversion from
