To convert a measurement in therms to a measurement in watt-hours, multiply the energy by the following conversion ratio: 29,307.107017 watt-hours/therm.

Since one therm is equal to 29,307.107017 watt-hours, you can use this simple formula to convert:

watt-hours = therms × 29,307.107017

The energy in watt-hours is equal to the energy in therms multiplied by 29,307.107017.

For example, here's how to convert 5 therms to watt-hours using the formula above.
watt-hours = (5 therms × 29,307.107017) = 146,535.535086 Wh

How Many Watt-Hours Are in a Therm?

There are 29,307.107017 watt-hours in a therm, which is why we use this value in the formula above.

1 therms = 29,307.107017 Wh

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.

What Is a Watt-Hour?

The watt-hour is a measure of electrical energy equal to one watt of power over a one hour period.

Watt-hours are usually abbreviated as Wh, although the formally adopted expression is W·h. The abbreviation W h is also sometimes used. For example, 1 watt-hour can be written as 1 Wh, 1 W·h, or 1 W h.

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]
