calorisch
Calorisch is a unit of measurement used to quantify the amount of heat energy in a substance. It is defined as the amount of heat required to raise the temperature of one gram of water by one degree Celsius. The term "calorie" is often used interchangeably with "calorisch," but the distinction is important in scientific contexts. The calorie, specifically the small calorie or gram calorie, is the amount of heat required to raise the temperature of one gram of water by one degree Celsius. In contrast, the kilocalorie, or large calorie, is the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius. Calorisch is commonly used in fields such as nutrition, where it is used to measure the energy content of food, and in thermodynamics, where it is used to quantify heat transfer. The symbol for calorisch is "cal."
