What are pounds per square inch and kilopascals?
Pounds per square inch is the imperial pressure unit, standard for US tires and plumbing. A kilopascal is 1,000 pascals, commonly used for tire and weather pressure. For reference: car tires run around 32 psi (220 kPa), and sea-level air pressure is about 101 kPa.
How to convert pounds per square inch to kilopascals
1 psi = 6.89476 kPa. To convert, multiply the number of pounds per square inch by 6.89476. For example, 5 psi = 34.4738 kPa, and 20 psi = 137.895 kPa. To go the other way, multiply kilopascals by 0.145038 (since 1 kPa = 0.145038 psi).
