kilojoules to kilocalories converterAbout These Units
kilocalories (kcal)
The kilocalorie (kcal) is what we colloquially call a 'Calorie' (capital C) on food labels in the US. It equals 1,000 small chemistry calories. It represents the energy required to heat 1 kilogram of water by 1°C. Confusion between calories and Calories is one of the most common unit errors in the world!
An apple contains about 95 kilocalories (Calories).
Commonly used in: US Food labels, Diet apps, Fitness trackers, Nutrition science, Body metabolic rate.
kilojoules (kJ)
The kilojoule (kJ) is the standard unit for food energy in most of the world (Australia, Europe, etc.), replacing the Calorie. One food Calorie (kcal) is approximately 4.2 kJ. It provides a more precise measure of energy intake than the large Calorie.
A slice of bread has about 300-400 kJ.
Commonly used in: Food labels (Global), Exercise machines, Diet planning, Thermodynamics, Metabolic rate tracking.
