Therms to Kilowatt Hours Conversion
Converting Therms (thm) to Kilowatt Hours (kWh) is a common energy and power conversion. 1 thm equals 29.305556 kWh. For example, 100 thm is equal to 2,930.555556 kWh.
Quick Mental Math: Therms to Kilowatt Hours
0.03412 therms is 1 kilowatt-hour, so use that as the mental anchor.
Why is converting Therms to Kilowatt Hours tricky?
therms to kilowatt hours uses an awkward ratio, so people often round too early or move the decimal the wrong way.
Quick Reference Values
1 thm = 29.305556 kWh. 5 thm = 146.527778 kWh. 10 thm = 293.055556 kWh. 25 thm = 732.638889 kWh. 50 thm = 1,465.277778 kWh. 100 thm = 2,930.555556 kWh.
What is Therms?
Therms (thm) is a unit of energy and power. A therm is a unit of heat energy equal to 100,000 British thermal units (BTUs). It converts to approximately 105.5 megajoules (MJ) in SI units. This unit is commonly used for measuring natural gas consumption and heating energy content in the United States and the United Kingdom [nist-si-guide]. The therm was introduced in the early 20th century as a practical energy unit for gas utilities, standardizing measurements of heat content based on BTUs. Its adoption helped unify commercial billing practices in the gas industry [nist-si-guide]. Therms are primarily used in North America and the UK for natural gas billing and energy reporting. They are recognized by the U.S. Energy Information Administration and British gas suppliers, though SI units predominate in scientific contexts [nist-si-guide].
What is Kilowatt Hours?
Kilowatt Hours (kWh) is a unit of energy and power. A kilowatt-hour (kWh) measures electrical energy equivalent to one kilowatt of power supplied for one hour. It equals 3.6 million joules and is the standard billing unit for electricity consumption worldwide [bipm-si-brochure]. The kilowatt-hour emerged with widespread electric power usage in the late 19th and early 20th centuries. It became standardized as electric utilities adopted it for consumer energy measurement and billing [bipm-si-brochure]. The kWh is the universal unit for residential and commercial electricity billing globally, including in North America, Europe, and Asia. It is used extensively in energy management, engineering, and environmental reporting [nist-si-guide].
Common Misspellings
People often search for this conversion using these alternate spellings: therm, thermes, thermses, kilowatt hour, kw/h, kwh, kilowatthour. All of these refer to the Therms to Kilowatt Hours conversion.
