Context values
Some unit families need one extra value for a physically accurate result.
Use the converter to see the formula.
kWh and Kilowatt measure different quantities, so no single result applies.

Formula
kWh (kWh) measures energy, while Kilowatt (kW) measures power. These are different physical quantities, so there is no single multiplication factor that converts one into the other.
kWh relates to its own energy base unit by a factor of 3600000. kW relates to its own power base unit by a factor of 1000.

Frequently asked questions
Can kWh be converted to Kilowatt?
Not directly. kWh measures energy and Kilowatt measures power. Converting between different physical quantities needs an extra physical relationship (such as area, distance, or time), not just a unit ratio.
What is kWh used for?
The kWh (kWh) is a unit of energy. A kilowatt-hour is 3.6 million joules.
What is Kilowatt used for?
The Kilowatt (kW) is a unit of power. Kilowatt is 1000 watt units.
Why does the converter show an incompatible units message?
The Universal Converter only calculates a numeric result when both units share the same physical dimension. Since kWh and Kilowatt don't, the tool flags them as not directly compatible rather than returning a meaningless number.
What should I convert kWh to instead?
Use another energy unit, such as one of the related kWh conversions linked below.
What should I convert Kilowatt to instead?
Use another power unit, such as one of the related Kilowatt conversions linked below.

About this conversion
This page compares kWh (kWh) and Kilowatt (kW) within the engineering converter.
A kilowatt-hour is 3.6 million joules. Kilowatt is 1000 watt units.
Because kWh measures energy and Kilowatt measures power, the two units are not directly convertible: there is no fixed ratio that turns one into the other without additional information.
The calculator above will report that these units are not compatible. For a working result, choose two units from the same measurement family — see the related conversions below.
