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 Calories?
Calories (cal) is a unit of energy and power. The calorie (cal) is defined as exactly 4.184 joules. It quantifies the energy needed to raise the temperature of one gram of water by 1°C under standard conditions. The calorie is widely used in chemistry and nutrition to express energy content [bipm-si-brochure]. The calorie was introduced in the early 19th century by Nicolas Clément and standardized internationally in the 20th century. It was adopted for practical energy measurement in chemistry and food science before the joule became the SI unit [bipm-si-brochure]. Calories remain common in food labeling, nutrition, and chemistry worldwide. The dietary Calorie (kcal) is prevalent in the US, Europe, and many countries while scientific contexts prefer the joule [bipm-si-brochure].
Common Misspellings
People often search for this conversion using these alternate spellings: therm, thermes, thermses, calorie, cal, calory, calo. All of these refer to the Therms to Calories conversion.
