When you need to convert kilopascals to pounds per square inch
- Setting tyre pressure from a placard quoted in psi, bar or kPa.
- Reading weather pressure, dive tables or industrial equipment ratings.
Common mistakes to avoid
- Dividing when you should multiply. Because 1 kilopascal = 0.145038 pounds per square inch, the answer should be smaller than the number you started with.
- Rounding too early. Convert first at full precision, then round the final answer to the precision the task actually needs.
How precise does the answer need to be?
Round only at the end, and only to the precision your task actually needs. The converter above keeps full double precision internally and rounds for display.
How these units are defined
- Kilopascal (kPa): 1,000 pascals; tyre pressures in metric countries. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
- Pound per square inch (psi): The dominant US pressure unit for tyres and plumbing. The accepted value is a measured or conventional figure rather than an exact definition, so the factor shown is rounded.
