How to Convert Watt-hours to Therms
To convert a watt-hour measurement to a therm measurement, multiply the energy by the conversion ratio. One watt-hour is equal to 3.4121E-5 therms, so use this simple formula to convert:
The energy in therms is equal to the watt-hours multiplied by 3.4121E-5.
Watt-hours and therms are both units used to measure energy. Keep reading to learn more about each unit of measure.
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.
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.
