## How to Convert Watt-seconds to Million BTU

To convert a watt-second measurement to a million BTU measurement, multiply the energy by the conversion ratio.

Since one watt-second is equal to 9.4782E-10 million BTU, you can use this simple formula to convert:

The energy in million BTU is equal to the watt-seconds multiplied by 9.4782E-10.

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

Watt-seconds and million BTU 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]}

## Million BTU

One million BTU is a measure of heat energy equal to 1,000,000 BTU, which are equal to the amount of heat energy required to increase the temperature of one pound of water one degree Fahrenheit.

The million BTU is a US customary unit of energy. Million BTU can be abbreviated as *MMBTU*; for example, 1 million BTU can be written as 1 MMBTU.
