Formula
Watt-hour (Wh) measures energy, while BTU per hour (BTU/h) measures power. These are different physical quantities, so there is no single multiplication factor that converts one into the other.
Wh relates to its own energy base unit by a factor of 3600. BTU/h relates to its own power base unit by a factor of 0.293071.
Conversion table
| Watt-hour (Wh) | 3600 × energy base unit |
| BTU per hour (BTU/h) | 0.293071 × power base unit |

Frequently asked questions
Can Watt-hour be converted to BTU per hour?
Not directly. Watt-hour measures energy and BTU per hour 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 Watt-hour used for?
The Watt-hour (Wh) is a unit of energy. A watt-hour is 3,600 joules.
What is BTU per hour used for?
The BTU per hour (BTU/h) is a unit of power. Power rate using BTU per hour.
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 Watt-hour and BTU per hour don't, the tool flags them as not directly compatible rather than returning a meaningless number.
What should I convert Watt-hour to instead?
Use another energy unit, such as one of the related Watt-hour conversions linked below.
What should I convert BTU per hour to instead?
Use another power unit, such as one of the related BTU per hour conversions linked below.

About this conversion
This page compares Watt-hour (Wh) and BTU per hour (BTU/h) within the engineering converter.
A watt-hour is 3,600 joules. Power rate using BTU per hour.
Because Watt-hour measures energy and BTU per hour 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.
