A kilocalorie (kcal) is equal to 1000 calories (cal). The term "Calorie" (with a capital C) that you see on food labels actually refers to kilocalories. So when a food label says 100 Calories, it means 100 kilocalories or 100,000 calories.
Nutrition information is presented differently in various countries and contexts. Some scientific measurements use calories (cal), while food packaging typically uses kilocalories (kcal or Cal). Converting between these units ensures accurate tracking of energy intake for diet management, scientific research, and nutritional analysis.
Our tool uses precise mathematical calculations based on the standard conversion factor (1 kcal = 1000 cal). Results are accurate to 6 decimal places, though we display up to 4 decimal places for better readability. The tool performs calculations in real-time as you type for maximum accuracy.
