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

To convert a british thermal unit measurement to a watt-hour measurement, multiply the energy by the conversion ratio. One british thermal unit is equal to 0.293071 watt-hours, so use this simple formula to convert:

The energy in watt-hours is equal to the british thermal units multiplied by 0.293071.

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

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

## 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.

## 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]}
