Calories to Kilojoules Chart: Your Ultimate Guide to Energy Conversion

Calories vs. Kilojoules: Understanding the Difference

Calories and kilojoules (kJ) are both units of energy, but they are not the same. A calorie is the amount of energy required to raise the temperature of one gram of water by one degree Celsius. A kilojoule is the amount of energy required to do the same thing for one kilogram of water.

One kilojoule is equal to 1,000 joules. One calorie is equal to 4.184 kilojoules. This means that one calorie is about 24% as much energy as one kilojoule.

In the United States, food labels list calorie content. However, in many other countries, food labels list kilojoule content. It is important to be aware of the difference between these two units of energy so that you can accurately compare food labels.

Calories to Kilojoules Chart

The following table provides a conversion chart for calories to kilojoules:

Converting Calories to Kilojoules

To convert calories to kilojoules, simply multiply the number of calories by 4.184. For example, to convert 100 calories to kilojoules, you would multiply 100 by 4.184. This would give you 418.4 kilojoules.

Converting Kilojoules to Calories

To convert kilojoules to calories, simply divide the number of kilojoules by 4.184. For example, to convert 418.4 kilojoules to calories, you would divide 418.4 by 4.184. This would give you 100 calories.

Applications for the Calories to Kilojoules Chart

The calories to kilojoules chart can be used for a variety of purposes, including:

• Comparing food labels from different countries
• Calculating the energy content of food
• Converting calorie intake goals to kilojoule intake goals
• Tracking energy expenditure

Conclusion

The calories to kilojoules chart is a valuable tool for anyone who wants to track their energy intake or支出。By understanding the difference between calories and kilojoules, you can make informed choices about the foods you eat and the activities you participate in.
