Kilopascals and pounds per square inch
Kilopascals (kPa) is a multiple of the pascals (Pa), the SI unit of pressure. One kPa is equal to 10^{3} Pa. It is used to measure pressure, stress, and elastic modulus. In Canada, meteorologists use kilopascals for weather reports.
Pounds per square inch (psi) is still used to measure pressure and stress in countries that use Imperial or US customary units, including the United States. One psi is the pressure caused by a poundforce load acting on one squareinch surface.
kPa to psi pressure conversion
Now that you're familiar with these units let's deal with kilopascals to psi conversion. The kPa to psi conversion factor is 0.1450377. So when converting pressure from kPa to psi, we must multiply it with 0.1450377.
For example, 40 kPa pressure in psi would be:
Now, let's consider how psi to kPa pressure conversion works. All we need to do is divide the pressure in psi by 0.1450377.
For instance, if the pressure reads 150 psi, the pressure in kPa would be:
