About kilojoules and kilocalories
The Conversion Formula
To convert kilojoules to kilocalories, multiply the value by the conversion factor: 1 kJ = 0.239006 kcal. For a worked example, suppose you need to convert 25 kJ to kilocalories: 25 × 0.239006 = 5.9751 kcal. To convert in the opposite direction, divide by 0.239006, or equivalently multiply by 4.184.
About kilojoules
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. kilojoules are commonly used in Food labels (Global), Exercise machines, Diet planning, and Thermodynamics, Metabolic rate tracking.
A slice of bread has about 300-400 kJ.
About kilocalories
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! kilocalories are commonly used in US Food labels, Diet apps, Fitness trackers, and Nutrition science, Body metabolic rate.
An apple contains about 95 kilocalories (Calories).
When Would You Convert kilojoules to kilocalories?
