thermie

Thermie is a unit of heat energy, specifically defined as the amount of heat required to raise the temperature of one gram of water by one degree Celsius. It is a non-SI unit of energy, but it is still used in some contexts, particularly in the field of thermodynamics and heat transfer. The term "thermie" is derived from the Greek word "thermos," which means heat.

The thermie is closely related to the calorie, another unit of heat energy. One thermie is equal to 100,000 calories. In the context of the International System of Units (SI), the joule is the standard unit of energy, and one thermie is approximately equal to 418.4 kilojoules.

Thermie is often used in the context of heat transfer and thermodynamics, particularly in the study of heat engines and refrigeration systems. It provides a convenient way to express the amount of heat energy involved in various processes, such as the heat of combustion of fuels or the heat of reaction in chemical processes.

Despite its usefulness, the thermie is not as widely used as the joule or the calorie in modern scientific and engineering contexts. However, it remains a recognized unit of heat energy and is still used in certain specialized applications.
