How to convert Kilowatt-hours to Watt-hours

1 Kilowatt-hours (kWh) is equal to 1000 Watt-hours (Wh).

1 kWh = 1000 Wh
or
1 Wh = 0.001 kWh

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 $10^3$ . 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 $10^3$ is representing Kilo prefix in kWh unit.

1 kWh = 10^3*Pt = 10^3*IVt = 3600 * 10^3*J = 2.247 * 10^{22} * 10^3 eV = 8.598*10^5 * 10^3 cal

$P - Power$
$t - Time \text{ (in hours. Multiply by 3600 to convert to seconds)}$
$I - Current$ $V - Volts$
$J - Joules$
$eV - Electronvolt$
$cal - Calories$
