Converting Pounds Per Square Inch or PSI to Atmospheres

This example problem demonstrates how to convert the pressure unit pounds per square inch (psi) to atmospheres (atm). PSI to Atm Problem A bicycle tire is inflated to 65 psi. What is this pressure in atmospheres?Solution:1 atm 14.696 psiSet up the conversion so the desired unit will be canceled out. In this case, we want atm to be the remaining unit.pressure in atm (pressure in psi) x (1 atm/14.696 psi)pressure in atm (65/14.696) atmpressure in atm 4.423 atmAnswer:The average sea level air pressure is 4.423 atm.
