Convert Kilopascals to Pounds per Square Inch
kPa to psi · pressure conversion
What are kilopascals and pounds per square inch?
A kilopascal is 1,000 pascals, commonly used for tire and weather pressure. Pounds per square inch is the imperial pressure unit, standard for US tires and plumbing. For reference: car tires run around 32 psi (220 kPa), and sea-level air pressure is about 101 kPa.
How to convert kilopascals to pounds per square inch
1 kPa = 0.145038 psi. To convert, multiply the number of kilopascals by 0.145038. For example, 5 kPa = 0.725189 psi, and 20 kPa = 2.90075 psi. To go the other way, multiply pounds per square inch by 6.89476 (since 1 psi = 6.89476 kPa).
