Why this conversion is exact
The exact factor behind this page: 1 kPa = 0.145038 psi. That value is a defined standard, not a measurement, so every conversion on this page is exact up to the digits shown. The most common practical error is mixing up which direction the factor runs: multiply when going from kPa to psi, divide when returning.
Rounding is display-only. The converter keeps full precision internally, so chained conversions (this unit to another and back) return to the starting value without drift, which hand-rounded tables cannot promise.
What you are converting
Kilopascal
A kilopascal is 1,000 pascals, the metric pressure unit. Real-world anchor: tire pressure in most countries reads 220-240 kPa.
Pound per square inch
Psi is the pressure of one pound of force on one square inch. Real-world anchor: car tires run at 30-35 psi.
Why convert and when you would use this
European and Asian car manuals quote kPa; US gauges read psi.
Worked example
Worked example: 10 kPa x 0.145038 = 1.4504 psi.
Rounding and accuracy
Use 2-4 decimal places for everyday tasks; keep more for engineering or lab precision.
