How the conversion works

Multiply by 1,000 to go from kilowatt-hour 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 kilowatt-hour — 1 Wh = 0.001 kWh.
