How to convert Watt-hours to Kilowatt-hours

1 Watt-hours (Wh) is equal to 0.001 Kilowatt-hours (kWh).

1 Wh = 0.001 kWh
or
1 kWh = 1000 Wh

What is watt-hours?

A watt-hour is a unit of energy and its units, Wh, are formed with W for watt and h for hour from SI unit system. Its definition, in the context of electricity, is the energy of one watt power flowing for one hour.

What is kilowatt-hours?

A Kilowatt-hour is a unit of energy and its units, kWh, are formed with W for watt and h for hour from SI unit system combined with letter k, metric prefix, for 1,000 or 10310^3. Its definition, in the context of electricity, is the energy of one watt power flowing for one hour.

Followings equivalent equations are identical but in different units. Please note that factor 10310^3 is representing Kilo prefix in kWh unit.
