1 kilowatt hour (kW h) (10^3 W) x (3600 s) =3.6 xx 10^(6) J=(3.6xx10^6)/( 1.6xx10^(-19)) eV ( because 1 eV= 1.6 xx 10^(-19 )) =2.25 xx 10^25 eV
A kilowatt-hour (kWh) is a unit of energy that represents the consumption of one kilowatt (kW) of power over a duration of one hour. In simpler terms, if you were to run an appliance that requires one kilowatt of power continuously for one hour, it would use one kilowatt-hour of ener...
NOTE For the purposes of this document, thermal energy and electric energy are expressed by the unit of "J" (Joule) and "Wh" (Watt hour) respectively unless otherwise noted, with a prefix of International System of Units (SI) if necessary. (1 J = 1 W·s, 1 Wh = 1 W·h = 3 ...
One watt is defined as the use or generation of 1 joule of energy per second. In an electrical circuit, a watt can also be defined as 1 ampere of current moving through a resistance at 1 volt of potential, and when charges move from a high voltage to a low voltage (a potential ...

Watt-Hour:A unit of energy equal to the total amount of energy that would be delivered in 1 hour of time if the rate of energy flow was 1 watt (one Joule per second). The number of watts times the number of hours equals the number of watt-hours. (Abbreviated Wh.) ...
The watt is a unit of power, which measures the rate of energy flow in J sec–1. Thus the watt-hour is a unit of energy. An average human consumes energy at a rate of about 100 watts; the brain alone runs at about 5 watts. 1 J = 2.78 × 10–4 watt-hr 1 w-h = 3.6 kJ...
