KWh to watts calculator FullScreen

Convert energy in kilowatt-hours (kWh) to power in watts (W). Ideal for understanding the rate of energy consumption and determining the power level based on energy usage. Obtain an estimation of watts from kilowatt-hours using this practical online tool.

Enter energy in kilowatt-hours: kWh
Enter time in hours: hr
Power result in watts: W


What is KWh to watts calculator

To convert kilowatt-hours (kWh) to watts (W), you need to know the time (t) in hours for which the energy is consumed. The formula for converting kilowatt-hours to watts is:

Watts (W) = Kilowatt-hours (kWh) / Time (t)

Simply divide the energy consumption in kilowatt-hours by the time period in hours to obtain the power in watts.

For example, if you have an energy consumption of 10 kWh over a duration of 5 hours, you can calculate the average power in watts as follows:

Watts (W) = 10 kWh / 5 hours Watts (W) = 2,000 W

In this example, the average power consumption is 2,000 watts.

It's important to note that watts represent power, which is the rate at which energy is transferred or used. When converting from kilowatt-hours to watts, it is necessary to consider the time period over which the energy is consumed. Additionally, if the power consumption is not constant, the average power over the given time period should be considered for a more accurate conversion.

KWh to watts calculation

The power P in watts (W) is equal to 1000 times the energy E in kilowatt-hours (kWh),

divided by the consumption time period t in hours (hr):

P(W) = 1000 × E(kWh) / t(hr)

KWh to watts calculator Example

To convert kilowatt-hours (kWh) to watts (W), you need to multiply the kilowatt-hour value by 1000. Since 1 kilowatt is equal to 1000 watts, this conversion can be done by multiplying the kWh value by 1000.

Here's an example that demonstrates the calculation:

Let's assume you have an energy consumption of 10 kWh.

Watts = 10 kWh * 1000 = 10,000 W

Therefore, the energy consumption of 10 kWh is equal to 10,000 watts.

This conversion is useful when you want to express energy usage in terms of its rate or power in watts rather than kilowatt-hours.
