What is a Kilowatt-Hour?

A kilowatt-hour, otherwise known as a kWh, is a way to measure how much energy you’re using.

It’s not the number of kilowatts you’re using in an hour, even though that seems to make sense. A kWh equals the amount of energy you would use by keeping a 1,000 watt appliance running for one hour. In metric, 1,000 = kilo, so 1,000 watts equals a kilowatt.

For instance, if you turned on a 100 watt bulb, it would take 10 hours to use one kilowatt-hour of energy. A 2,000 watt appliance, on the other hand, would only take half an hour. It all comes down to dividing the number of watts in an appliance into 1,000.

What Is A Kilowatt? 

A kilowatt is a unit of energy that carries a lot of significance in everyday life — it’s the base unit used in the routine measurement for electrical energy. All the appliances and gadgets in your home consume electricity measured in kilowatts.

How to convert kilowatts-hour to kilowatts

You can calculate kilowatt from kilowatt-hour and hours, but you can’t convert kilowatt-hour to kilowatt, since kilowatt-hour and kilowatt units represent different quantities.

Kilowatts-hour to kilowatts calculation formula

The power P in kilowatts (kW) is equal to the energy E in kilowatt-hour (kWh), divided by the time period t in hours (hr):

P_(kW) = E_(kWh) / t_(hr)

So

kilowatt = kilowatt-hour / hour

or

kW = kWh / h

Example

What is the power consumption in kilowatts when the energy consumption is 15 kilowatt-hour for time duration of 3 hours?

P = 15 kWh / 3 h = 5 kW
