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

To convert a measurement in british thermal units to a measurement in watt-seconds, multiply the energy by the following conversion ratio: 1,055.055853 watt-seconds/british thermal unit.

Since one british thermal unit is equal to 1,055.055853 watt-seconds, you can use this simple formula to convert:

watt-seconds = british thermal units × 1,055.055853

The energy in watt-seconds is equal to the energy in british thermal units multiplied by 1,055.055853.

For example, here's how to convert 5 british thermal units to watt-seconds using the formula above.
watt-seconds = (5 BTU × 1,055.055853) = 5,275.279263 Ws

### How Many Watt-Seconds Are in a British Thermal Unit?

There are 1,055.055853 watt-seconds in a british thermal unit, which is why we use this value in the formula above.

1 BTU = 1,055.055853 Ws

## What Is a British Thermal Unit?

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.

## What Is a Watt-Second?

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]
