How to Convert British Thermal Units to Watt-seconds

To convert a british thermal unit measurement to a watt-second measurement, multiply the energy by the conversion ratio. One british thermal unit is equal to 1,055.055853 watt-seconds, so use this simple formula to convert:

watt-seconds = british thermal units × 1,055.055853

The energy in watt-seconds is equal to the 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.
5 BTU = (5 × 1,055.055853) = 5,275.279263 Ws

British thermal units and watt-seconds 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.


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 can be abbreviated as Ws, for example 1 watt-second can be written as 1 Ws.
