How the conversion works
Multiply by 100 to go from bar to kilopascal, or divide by it to go back. Every conversion on this site routes through the SI value (Pa) rather than a table of pairwise factors, so a round-trip returns exactly what you started with.
Going the other way? kilopascal to bar: 1 kPa = 0.01 bar.
