How the conversion works
Multiply by 1.162222222 to go from kilocalorie to watt-hour, or divide by it to go back. Every conversion on this site routes through the SI value (J) rather than a table of pairwise factors, so a round-trip returns exactly what you started with.
Going the other way? watt-hour to kilocalorie — 1 Wh = 0.8604206501 kcal.
