# How to convert kWh to watts

How to convert energy in kilowatt-hour (kWh) to electric power in watts (W).

You can calculate watts from kilowatt-hour and hours. You can't convert kilowatt-hour to watt unit since kilowatt-hour and watt units represent different quantities.

### Kilowatts-hour to watts calculation formula

To convert energy in kilowatt-hours (kWh) to electric power in watts (W), you can use the following formula:

`P(W) = 1000 × E(kWh) / t(hr)`

So

`watt = kilowatt-hour / hour`

or

`W = 1000 × kWh / h`

#### Example

where

`P is the power in watts, `

`E is the energy in kilowatt-hours,`

`t is the time period in hours.`

To use the formula, simply substitute the values for E and t into the equation and solve for P.

For example, if you have an energy consumption of 15 kilowatt-hours for a time duration of 4 hours, you can calculate the power consumption in watts like this:

`P = 1000 × 15 kWh / 4 h = 3750 W`

This means that the power consumption in the time period is 3750 watts.

It's important to note that the time period must be in hours to use this formula. If the time period is in a different unit of time, you'll need to convert it to hours first. For example, if the time period is in minutes, you can convert it to hours by dividing the number of minutes by 60.
