                                The word "calorie" stems from the Latin *calor*, meaning "heat," and its formal use as a unit of energy can be traced back to the early 19th century. French chemist and physicist Nicolas Clément is credited with creating the concept of calories and introducing the term around 1824, initially to explain the efficiency of steam engines.
