Etymology Origin:
The word "calorie" originates from Latin calor (heat), reflecting its original scientific use to measure heat energy. Introduced in the 19th century by French chemist Nicolas Clément, it was adopted into English to quantify the energy produced by food metabolism. The suffix "-ie" standardizes it as a measurable unit, aligning with other scientific terms like "energy" and "temperature."
