How the conversion works
Multiply by 0.001 to go from watt-hour to kilowatt-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? kilowatt-hour to watt-hour — 1 kWh = 1,000 Wh.
