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

Formula
BTU (BTU) 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.
BTU relates to its own energy base unit by a factor of 1055.06. kW relates to its own power base unit by a factor of 1000.

Frequently asked questions
Can BTU be converted to Kilowatt?
Not directly. BTU 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 BTU used for?
The BTU (BTU) is a unit of energy. British thermal unit.
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 BTU and Kilowatt don't, the tool flags them as not directly compatible rather than returning a meaningless number.
What should I convert BTU to instead?
Use another energy unit, such as one of the related BTU 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 BTU (BTU) and Kilowatt (kW) within the engineering converter.
British thermal unit. Kilowatt is 1000 watt units.
Because BTU 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.
