To an accuracy of two decimal places, 100 kPa is equal to 14.50 psi. According to the University of Florida, 1 psi = 6.89 kPa, which means that 100 kPa = 100/6.89 psi = 14.50 psi.
The units kPa (kilopascal) and psi (pounds per square inch) are units of pressure. The pascal unit (abbreviated as Pa) is part of the International System of Units (SI units) and is equal to one Newton of force per square meter of area. One kPa is equal to 1,000 Pa. One psi is equal to one pound of pressure per square inch of area.
