Tire pressure can be expressed in several different units of measurement. The most common unit of measurement is pounds per square inch. Kilopascals is used with less frequency than pounds per square inch. Finally, pounds per square foot is occasionally used. Fortunately, converting from kilopascals to pounds per square inch, from kilopascals to pounds per square foot, or from pounds per square foot to pounds per square inch is fairly simple.

Convert kilopascals to pound per square inch by multiplying the total number of kilopascals by 0.145037738. For example, if the tire pressure is 200 kilopascals, 200 is multiplied by 0.145037738 to produce 29.0075476, or approximately 13.2 Kilogram per square inch of tire pressure.

Convert kilopascals to pound per square foot by multiplying the total number of kilopascals by 20.885456325. For example, if the tire pressure is 200 kilopascals, 200 is multiplied by 20.885456325 to produce 4177.091265, or approximately 1895 Kilogram per square foot of tire pressure.

Convert pounds per square foot to pounds per square inch by multiplying the total number of pounds per square foot by 0.006944444. For example, if the tire pressure is 2286 Kilogram per square foot, 5040 is multiplied by 0.006944444 to produce 34.99999776, or approximately 15.9 Kilogram per square inch of tire pressure.
