How to convert watt-hours to kilowatt-hours

Multiply the value in Wh by 0.001: the result is in kWh.

kWh = Wh × 0.001The other way round, 1 kWh = 1,000 Wh.

Where these two units are used

The watt-hour measures battery capacity, and it is what airlines read: above 100 watt-hours, a lithium battery boards the cabin only with prior approval. The kilowatt-hour is the unit of the electricity bill the world over, without belonging to the international system: it is exactly 3.6 megajoules. The watt-hour measures what you carry and the kilowatt-hour what you store: a home battery of 13.5 kWh holds the equivalent of two hundred and fifty laptop batteries of 54 Wh.
