calorie
calorie
Noun
pl: calories
This term is used in two distinct contexts: nutritional and scientific. In common parlance, it refers to the energy derived from food, though this is technically a kilocalorie (1,000 small calories). It carries a strong association with health, weight management, and metabolic processes.
In a laboratory setting, it refers to a precise thermodynamic measurement of heat. Because it is a standard unit of measurement, it follows regular countability rules, though it is often used in the plural when discussing dietary intake or energy totals.
