Enter power in kilowatts: kW
Enter time in hours: h
Energy result in kilowatt-hours: kWh


What is Kilowatts to kilowatt-hours calculator

Converting kilowatts (kW) to kilowatt-hours (kWh) requires knowledge of the time (t) in hours for which the power is consumed. The formula for converting kilowatts to kilowatt-hours is:

Kilowatt-hours (kWh) = Kilowatts (kW) x Time (t)

To use this formula, multiply the power consumption in kilowatts by the time period in hours.

For example, if you have a device that consumes 2 kilowatts of power for 5 hours, you can calculate the energy usage in kilowatt-hours as follows:

Kilowatt-hours (kWh) = 2 kW x 5 hours Kilowatt-hours (kWh) = 10 kWh

In this example, the energy usage is 10 kilowatt-hours.

It's important to note that kilowatt-hours represent energy, which is the amount of power consumed over time. This conversion assumes that the power remains constant throughout the entire duration. If the power consumption varies over time, the calculation should consider the average power or integrate the power over each time interval to obtain an accurate measurement of energy usage.

KW to kilowatt-hours calculation

The energy E in kilowatt-hours (kWh) is equal to the power P in kilowatts (kW), times the time period t in hours (h):

E(kWh) = P(kW) × t(h)

Kilowatts to kilowatt-hours calculator Example

To convert kilowatts (kW) to kilowatt-hours (kWh), you need to know the duration of time for which the power is consumed. The formula to calculate kilowatt-hours from kilowatts and time is:

kWh = kW * hours

Here's an example that demonstrates the calculation:

Let's assume you have a power consumption of 2 kW for a duration of 5 hours.

kWh = 2 kW * 5 hours = 10 kWh

Therefore, the energy consumption in kilowatt-hours corresponding to a power consumption of 2 kW for 5 hours would be 10 kWh.

This calculation is commonly used to determine the total energy usage or electricity consumption over a specific period of time.
