Please visit pressure conversion to convert all pressure units. The altitude at a given air pressure can be calculated using Equation 1 for an altitude up to 11 km. Due to the fact that weather conditions affect pressure and altitude calculations, the pressure and temperature at sea level must be known. 1 atm 760 torr 14.696 psi 1.013 bar Pounds per square inch (psi) was commonly used in the U.K. 1 psi = 0.0680459637 atm.Ītm (atmospheric pressure) is the force per unit area by the weight of air above that point. Using ISA standards, the defaults for pressure and temperature at sea level are 101,325 Pa and 288 K. Psi (Pound Force Per Square Inch) Conversion: Psi is a pressure unit and equals to the force of one pound applied to one square inch. To convert atm to psi, multiply the atm value by 14.6959488.
PSI TO ATM HOW TO
To convert psi to atm, multiply the psi value by 0.06804596379 or divide by 14.6959488.įor example, to convert 100 psi to atm, divide 100 by 14.6959488, that makes 100 psi is 6.80459639 atm.Ītm = psi / 14.6959488 How to convert atm to psi (pound force per square inch)?ġ Atm (atmospheric pressure) is equal to 14.6959488 psi. Convert Pounds per Square Inch to Atmoshperes How many is 1 Pound per square inch in Atmospheres 1 Pound per square inch equals 0.07 Atmospheres (1psi 0.07. How to convert psi to atm (atmospheric pressure)?ġ Psi (pound force per square inch) is equal to 0.06804596379 atm. It is wrong to conclude that 2 PSIA is equal to -27.4 PSIG this is not how the PSIA to PSIG conversion works. Note about wrong conversion: 1 PSIA is equal to -13.7 PSIG.
As we can see, at sea level, 80 PSIA is equal to 65.3 PSIG. Formula: multiply the value in pounds per square inch by the conversion factor 0.068045963779857. Alternatively, to find out the atmospheric pressure value for the most commonly converted psi values, you may check the psi to atm conversion table.īelow, you will find information of how to convert psi to atm and how to convert atm to psi, including the formulas and example conversions. Here is how we can calculate this using PSIG to PSIA formula at sea level: 80 PSIA 14.7 PSI 65.3 PSIG. To convert pound force per square inch (psi) to atmospheric pressure (atm), you may use the psi to atm converter above.
