In practice
PSI to kilopascals multiplies by 6.89476, because one pound per square inch equals 6,894.76 pascals. Tyre pressures are given in kPa in many countries — 32 psi is 221 kPa, and 35 psi is 241 kPa — and sometimes in bar, where 100 kPa is one bar. It is also used for water pressure at a tap: 40 to 60 psi (275 to 415 kPa) is typical for homes. Check the unit on both the gauge and the specification before inflating.
How to convert psi to kilopascals
