About the kilocalorie
The kilocalorie, often written as "Calorie" with a capital C, became the standard for food energy in the United States through early 20th-century nutrition science.
In everyday use the kilocalorie appears in nutrition labels, diet planning, and exercise tracking. As a point of reference: an average adult needs about 2000 kcal per day.
