201 kJ is equal to approximately 48.08 kcal.
To convert kilojoules (kJ) to kilocalories (kcal), you divide the energy value in kJ by 4.184, since 1 kcal equals 4.184 kJ. Using this, 201 kJ converts to about 48.08 kcal.

Conversion Formula
The formula to convert kilojoules (kJ) to kilocalories (kcal) is:
kcal = kJ ÷ 4.184
This works because one kilocalorie is defined as the amount of energy needed to raise the temperature of one kilogram of water by one degree Celsius, which equals 4.184 kilojoules. So when you have energy in kilojoules, dividing by 4.184 changes the unit into kilocalories.
For example, converting 201 kJ:
- Start with 201 kJ
- Divide by 4.184: 201 ÷ 4.184 = 48.079 kcal
- The result is approximately 48.08 kcal
Conversion Example
- Convert 350 kJ to kcal:
- Take 350 kJ
- Divide by 4.184: 350 ÷ 4.184 = 83.63 kcal
- Final result: 83.63 kcal
- Convert 120 kJ to kcal:
- Start with 120 kJ
- 120 ÷ 4.184 = 28.68 kcal
- Answer: 28.68 kcal
- Convert 500 kJ to kcal:
- 500 kJ divided by 4.184
- 500 ÷ 4.184 = 119.55 kcal
- Resulting in 119.55 kcal
- Convert 90 kJ to kcal:
- 90 ÷ 4.184 = 21.52 kcal
- This means 90 kJ equal about 21.52 kcal

Conversion Definitions
kJ (kilojoule): A kilojoule is a unit of energy in the metric system, representing 1000 joules. Joule is the SI derived unit for energy, measuring work or heat. Kilojoules are often used in food energy labeling and physics to express energy amounts, heat, or work done.
kcal (kilocalorie): A kilocalorie is a unit of energy commonly used to quantify food energy. One kilocalorie equals the amount of heat needed to raise one kilogram of water by one degree Celsius, equal to 4184 joules or 4.184 kilojoules. Often called “Calorie” with uppercase C in nutrition.
Conversion FAQs
Why do we divide kilojoules by 4.184 to get kilocalories?
The division by 4.184 comes from the exact relationship between the two energy units. Since 1 kcal equals 4.184 kJ, dividing energy in kJ by 4.184 converts it to kcal. It’s a direct unit conversion factor, not an approximation.
Can I convert kcal back to kJ using the same method?
Yes, but in reverse. To convert kcal to kJ, multiply the kcal value by 4.184. This reverses the division process, converting kilocalories to kilojoules accurately.
Are kilojoules and kilocalories interchangeable in food labels?
They represent energy but are not interchangeable without conversion. Different countries prefer one unit over another. For accurate energy intake, converting between them is necessary, as 1 kcal equals 4.184 kJ.
Is the conversion factor always exactly 4.184?
Yes, by definition the conversion factor is exact. This number comes from the physical properties of water and energy units, so it doesn’t change or vary depending on context.
Does converting kJ to kcal affect nutritional values?
No, the conversion only changes the unit of measure, not the energy content itself. Nutritional values stay the same, but the number looks different depending on which unit is used.
