Kilowatt-hours (kWh) measure total energy consumed, while kilowatts (kW) measure the rate of that consumption — the kWh to kW Calculator converts between the two. Enter your Energy (kWh) and the Time Period (hours) over which it was used to find the Average Power in kW, with the result also shown in watts.

A kilowatt-hour (kWh) is a unit of energy that measures the total amount of electricity consumed over time. A kilowatt (kW) is a unit of power that measures the rate of energy consumption at any given moment. Think of kWh as the total distance traveled, while kW is like the speed at which you're traveling.
To convert kWh to kW, divide the energy in kilowatt-hours by the time period in hours. The formula is: Power (kW) = Energy (kWh) ÷ Time (hours). For example, if you consumed 48 kWh over 24 hours, the average power would be 48 ÷ 24 = 2 kW.
Solar users need to understand both energy production (kWh) and power capacity (kW) to properly size their systems. kWh tells you how much energy your solar panels produced over time, while kW helps you understand the instantaneous power output needed to meet your energy demands.
Yes, you can use any time period in hours. Whether it's minutes (convert to decimal hours), days (multiply by 24), or months, just ensure your time input is in hours for accurate results.
This conversion is useful for sizing electrical equipment, calculating average power consumption of appliances, determining solar panel requirements, analyzing electricity bills, and understanding power demands for battery systems.
The calculated kW value represents the average power over the specified time period. It assumes constant power consumption throughout the entire duration. Actual instantaneous power may vary significantly from this average.
