Understanding kcal vs kJ
Depending on where you live in the world, nutritional energy is measured differently. In the United States and parts of Europe, food energy is almost exclusively discussed in "calories" (technically kilocalories or kcal). However, in Australia, New Zealand, and many other metric-standardized nations, the standard unit of food energy is the kilojoule (kJ).
The Conversion Formula
The mathematical conversion between these two units of energy is straightforward:
- 1 kcal = 4.184 kJ
- 1 kJ = 0.239 kcal
For example, a standard Starbucks Grande Latte with 2% milk is roughly 190 kcal. Using the formula (190 × 4.184), this equates to approximately 795 kilojoules.

Frequently Asked Questions
What is the difference between kcal and calories?
In nutritional science, 'calories' on food labels are technically kilocalories (kcal). Therefore, 1 dietary Calorie is exactly equal to 1 kcal. Both terms are used interchangeably in the US to denote food energy.
How do you convert kilojoules (kJ) to calories (kcal)?
To convert kilojoules to kilocalories, divide the kJ value by 4.184 (or multiply by 0.239). For example, a 1,000 kJ Starbucks sandwich is approximately 239 kcal.
