What is Kilocalorie?

The kilocalorie equals 1,000 thermochemical calories and is the standard unit for food energy labeling in Japan, the United States, and many other countries. It is often written as "Cal" (with a capital C) or simply called a "Calorie" on food packages. A bowl of rice (150 grams) contains about 235 kcal, a slice of bread about 160 kcal, and 30 minutes of walking burns roughly 100 kcal.

What is Calorie (thermochemical)?

The thermochemical calorie is a unit of energy originally defined as the amount needed to raise the temperature of one gram of water by one degree Celsius. It is exactly 4.184 joules. Note that the "Calorie" seen on food labels is actually a kilocalorie (1,000 calories). The calorie has deep roots in calorimetry and chemistry, and although the SI system favors joules, calories remain widely used in everyday discussions of food and diet.
