16 kilojoules (kj) is equal to approximately 3.8239 calories.
This conversion is done by multiplying the energy value in kilojoules by the factor 0.239006, which converts kj into calories. Since 1 kj equals about 0.239006 calories, multiplying 16 kj by this number gives the calorie equivalent.

Conversion Formula
The formula to convert kilojoules (kj) to calories is:
Calories = Kilojoules × 0.239006
This works because 1 kilojoule equals approximately 0.239006 calories. The calorie is a smaller unit of energy compared to the kilojoule. So, multiplying the kj value by 0.239006 converts the larger unit into the smaller, calories.
For example, converting 16 kj to calories:
- Start with 16 kj
- Multiply 16 by 0.239006
- 16 × 0.239006 = 3.824096 calories (rounded to 3.8239)
This formula lets you change any kilojoule value into calories by simple multiplication.

- Answer about 1.1950 calories
- Convert 100 kj to calories:
- Multiply 100 by 0.239006
- 100 × 0.239006 = 23.9006 calories
- Answer approximately 23.9006 calories
- Convert 0.5 kj to calories:
- Multiply 0.5 by 0.239006
- 0.5 × 0.239006 = 0.119503 calories
- Answer about 0.1195 calories
- Convert 40 kj to calories:
- Multiply 40 by 0.239006
- 40 × 0.239006 = 9.56024 calories
- Answer around 9.5602 calories

Conversion Definitions
kj (kilojoule): Kilojoule is a unit of energy in the metric system equal to 1,000 joules. It measures the amount of work done or heat transferred, commonly used in food energy content and physics. One kj equals approximately 0.239 calories, representing a larger energy unit than calorie.
calories: A calorie is a unit of energy used to quantify the amount of heat or energy food provides. There are two types: the small calorie used in chemistry, and the large Calorie (kilocalorie) used in nutrition. One calorie equals about 4.184 joules, making it smaller than a kilojoule.
Conversion FAQs
Why is the conversion factor 0.239006 for kj to calories?
The factor 0.239006 comes from the relationship between joules and calories. Since 1 calorie equals 4.184 joules, dividing 1,000 joules (1 kj) by 4.184 gives approximately 239.006 calories per 1,000 joules, or 0.239006 calories per 1 joule. This factor converts kj directly to calories.
Can I convert calories back to kilojoules easily?
Yes, converting calories to kilojoules requires dividing the calorie value by 0.239006 or multiplying by approximately 4.184. This reverses the conversion and gives you the energy in kilojoules. The calculator and formula work both ways with adjusted factors.
Are calories and kilojoules interchangeable in food labels?
They represent the same energy but differ in units. In food labels, calories often mean kilocalories (Calories with capital C), while kilojoules are metric units. Depending on region, one or the other is displayed, but both quantify energy intake or expenditure.
Does temperature affect the kj to calorie conversion?
No, the conversion between kilojoules and calories is a fixed mathematical ratio based on energy units, unaffected by temperature changes. It’s a constant relationship derived from physical constants, so temperature doesn’t influence the conversion factor.
What happens if I enter negative kilojoules in the conversion tool?
Negative kilojoule values represent energy loss or deficit, and the tool will convert them to negative calorie values accordingly. This can be useful when calculating energy burned or deficit in metabolism or exercise contexts.
