Best Answer

It is a unit of energy. If energy is transferred at a rate (power) of one kilowatt, during one hour, then one kilowatt-hour (kilowatt times hour) of energy will be transferred. Since a joule is equal to a watt-second, a kilowatt-hour is the same as 3.6 million joules.

The "kilowatt hour" is a unit of energy.

It's the amount of energy used when energy is flowing at the rate of 1,000 watts for 1 hour.

How may gallons per minute for a KWh?

There is no equivalence. A gallon is a measure of volume while a kilowatthour is a measure of energy. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid without some addition information.

How are electricity and related?

Electrical energy is a form of energy, and can be measured in the same units, Joules in the SI system. Note that 1 watt = 1 Joule/sec. Electrical energy is often expressed in Kilowatthours or Megawatthours, which are the normal ways an electric company measures your usage. 1 Kilowatthour just means a steady power of 1 kilowatt maintained for 1 hour. Since there are 3600 seconds in an hour, 1 kilowatthour = 3600 kilowattseconds. Now 1 watt = 1 Joule/sec, so 1 Joule = 1 wattsec, 1000 joules = 1 kilowattsec, so 3600 kilowattsecs = 1000 x 3600 Joules = 3.6 x 106 Joules = 1 kilowatthour.
