Therms to Watt-hours Conversion

Therms

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.

Watt-hours

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]
