Convert calorie (IT) to therm (US)
Please provide values below to convert calorie (IT) [cal (IT)] to therm (US) [thm (US)], or Convert therm (US) to calorie (IT).
1 cal (IT) = 3.96926822424e-08 thm (US). To convert calorie (IT) to therm (US), multiply the value by 3.96926822424e-08; to go the other way, divide by it (1 thm (US) = 25193560.7146 cal (IT)). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Calorie (It)
The calorie (cal) is a unit of energy traditionally used to quantify the amount of heat required to raise the temperature of one gram of water by one degree Celsius at standard atmospheric pressure.
History/Origin
The calorie was originally defined in the 19th century as a unit of heat energy in thermodynamics. It has historically been used in nutrition and physics, but has largely been replaced by the joule in scientific contexts. The 'small calorie' (cal) is distinct from the 'large calorie' (kcal), which is commonly used in food energy labeling.
Current Use
Today, the calorie is primarily used in nutrition to measure the energy content of foods and beverages, although the SI unit of energy, the joule, is increasingly preferred in scientific and technical fields.
Therm (Us)
The therm (US) is a unit of energy used primarily to measure natural gas consumption, equivalent to 100,000 British thermal units (BTUs).
History/Origin
The therm was introduced in the early 20th century as a practical unit for billing natural gas, standardizing energy measurement in the United States. It has been widely adopted in the energy industry for commercial and residential gas usage.
Current Use
Today, the therm (US) is still used in the natural gas industry for billing and energy calculations, although it has been largely supplemented by the gigajoule and other SI units in scientific contexts.
