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

To convert a watt-second measurement to a british thermal unit measurement, multiply the energy by the conversion ratio. One watt-second is equal to 0.000948 british thermal units, so use this simple formula to convert:

The energy in british thermal units is equal to the watt-seconds multiplied by 0.000948.

**For example,**here's how to convert 5,000 watt-seconds to british thermal units using the formula above.

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

## Watt-seconds

The watt-second is a measure of electrical energy equal to one watt of power over a one second period. One watt-second is equal to 1/3,600 of a watt-hour or one joule.

Watt-seconds are usually abbreviated as *Ws*, although the formally adopted expression is *W·s*. The abbreviation *W s* is also sometimes used. For example, 1 watt-second can be written as 1 Ws, 1 W·s, or 1 W s.

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.
