Calories are units that measure energy. In nutrition, calories can be found in food and drinks. There are two units related to calories: kilocalories (kcal) and calories (cal). A kilocalorie is 1,000 calories, and it is often used in dietary contexts to make the numbers easier to manage. Sometimes we need to convert kcal to cal to understand the energy content in food better. In this topic, we will learn how to convert kilocalories to calories.
A kilocalorie (kcal) is a unit of energy measurement commonly used in nutrition to quantify the energy content in food. It is equivalent to 1,000 small calories (cal). In dietary contexts, kilocalories are often referred to simply as "calories," which can be confusing.
The symbol for kilocalories is kcal, and it is typically used on food packaging to indicate energy content.
A calorie (cal) is a smaller unit of energy measurement. It is often used in scientific contexts rather than in everyday dietary discussions.
One kilocalorie equals 1,000 calories. The symbol for calories is cal.
To convert kilocalories to calories, we use the following formula: 1 kilocalorie = 1,000 calories
Calories = So, to convert from kilocalories to calories, you multiply the number of kilocalories by 1,000.
Conversely, to convert from calories to kilocalories, you divide the number of calories by 1,000.
Converting kilocalories (kcal) to calories (cal) is straightforward using a standard conversion factor. Since 1 kilocalorie is equal to 1,000 calories, we can convert kilocalories to calories by multiplying the number of kilocalories by 1,000.
Steps to convert kcal to cal:
1. Write down the energy in kilocalories.
2. Multiply the value by 1,000 to get the energy in calories.
Formula: Calories =
When we calculate energy, sometimes we use kilocalories (kcal) and sometimes calories (cal). Simple conversions help us understand how much energy something in kilocalories is in calories.
Below is a chart that shows us the kilocalorie-to-calorie conversions.
When converting kilocalories to calories, people often make mistakes. Here are some common mistakes to help understand the concepts of conversions better.
Convert 3.5 kcal to Cal
3.5 kcal = 3,500 cal
We know the conversion factor: 1 kcal = 1,000 cal
Now, multiply 3.5 by the conversion factor: 3.5 × 1,000 = 3,500 cal.
Convert 0.46 kcal to cal.
Solution: Converting 0.46 kcal to calories gives us 460 cal.
Use the conversion factor: 1 kcal = 1,000 cal 0.46 × 1,000 = 460 cal
A snack contains 1.2 kcal. What is the energy content in calories?
The energy content of the snack is 1,200 calories.
Convert 1.2 kcal to calories: 1.2 kcal = 1.2 × 1,000 = 1,200 calories
Energy = 1,200 calories.
The drink has 0.18 kcal. What is its energy content in calories?
The energy content in calories is 180 cal.
Convert 0.18 kcal to calories: 0.18 kcal = 0.18 × 1,000 = 180 cal
Energy = 180 cal (approximately).
Converting 9.9 kcal to Cal
9.9 kcal = 9,900 cal
Step 1: Use the conversion factor. 1 kcal = 1,000 cal
Step 2: Multiply 9.9 by 1,000. 9.9 × 1,000 = 9,900 cal
