Cómo funciona Julios a Calorías
The calorie and the joule both measure energy. One thermochemical calorie equals 4.184 joules, so to convert joules to calories you divide by 4.184.
The food Calorie shown on nutrition labels is actually a kilocalorie (kcal) — 1,000 small calories, or 4,184 joules. This converter shows both so you can move between physics and nutrition units.
cal = J ÷ 4.184kcal = J ÷ 41841 cal = 4.184 J · 1 kcal (food Calorie) = 4,184 J = 4.184 kJ
