This example problem demonstrates how to convert the pressure unit pounds per square inch (psi) to pascals (Pa).
The average air pressure at sea level is 14.6 psi. What is this pressure in Pa?
1 psi = 6894.7 Pa
Set up the conversion so the desired unit will be cancelled out. In this case, we want Pa to be the remaining unit.
pressure in Pa = (pressure in psi) x (6894.7 Pa/1 psi)
pressure in Pa = (14.6 x 6894.7) Pa
pressure in Pa = 100662.7 Pa
The average sea level air pressure is 100662.7 Pa or 1.0 x 105 Pa.
