## How to Convert Watt-Seconds to Therms

To convert a measurement in watt-seconds to a measurement in therms, multiply the energy by the following conversion ratio: 9.4782E-9 therms/watt-second.

Since one watt-second is equal to 9.4782E-9 therms, you can use this simple formula to convert:

therms = watt-seconds × 9.4782E-9

The energy in therms is equal to the energy in watt-seconds multiplied by 9.4782E-9.

**For example,**here's how to convert 500,000,000 watt-seconds to therms using the formula above.

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

## 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]}

## What Is a Therm?

One therm is a measure of heat energy equal to 100,000 BTU, which are equal to the amount of heat energy required to increase the temperature of one pound of water one degree Fahrenheit. Therms are often used by natural gas companies to measure the heat equivalent of gas used.

The therm is a US customary unit of energy.
