## How to Convert Watt-hours to British Thermal Units

To convert a watt-hour measurement to a british thermal unit measurement, multiply the energy by the conversion ratio. One watt-hour is equal to 3.412142 british thermal units, so use this simple formula to convert:

The energy in british thermal units is equal to the watt-hours multiplied by 3.412142.

**For example,**here's how to convert 5 watt-hours to british thermal units using the formula above.

Watt-hours and british thermal units are both units used to measure energy. Keep reading to learn more about each unit of measure.

## Watt-hours

The watt-hour is a measure of electrical energy equal to one watt of power over a one hour period.

Watt-hours are usually abbreviated as *Wh*, although the formally adopted expression is *W·h*. The abbreviation *W h* is also sometimes used. For example, 1 watt-hour can be written as 1 Wh, 1 W·h, or 1 W h.

In formal expressions, the centered dot (·) or space is used to separate units used to indicate multiplication in an expression and to avoid conflicting prefixes being misinterpreted as a unit symbol.^{[1]}

## British Thermal Units

British thermal units are a measure of heat energy. Specifically, one british thermal unit is equal to the amount of heat energy required to increase the temperature of one pound of water one degree Fahrenheit. They are often used as a way to rate the energy heat producing appliances such furnaces, and to price heating fuels such as natural gas.

The british thermal unit is a US customary unit of energy. British thermal units can be abbreviated as *BTU*; for example, 1 british thermal unit can be written as 1 BTU.
