How the conversion works
Multiply by 3.38638864 to go from inch of mercury 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 inch of mercury — 1 kPa = 0.295299833 inHg.
