Conversion Formula
The formula to convert kilojoules (kj) into kilocalories (kcal) is:
kcal = kj × 0.239006
This formula works by multiplying the given energy value in kilojoules by the constant 0.239006, which represents the number of kilocalories per kilojoule. The factor comes from the relationship between joules and calories where 1 calorie equals approximately 4.184 joules.
Step-by-step calculation for 201 kj:
- Start with 201 kj.
- Multiply 201 by 0.239006.
- 201 × 0.239006 = 48.063206.
- Rounded to four decimals, 48.0632 kcal.
Conversion Example
- Example 1: Convert 150 kj to kcal
- Multiply 150 by 0.239006.
- 150 × 0.239006 = 35.8509 kcal.
- Result is about 35.8509 kcal.
- Example 2: Convert 250 kj to kcal
- Multiply 250 by 0.239006.
- 250 × 0.239006 = 59.7515 kcal.
- The energy is approximately 59.7515 kcal.
- Example 3: Convert 300 kj to kcal
- Multiply 300 by 0.239006.
- 300 × 0.239006 = 71.7018 kcal.
- The converted value is 71.7018 kcal.
- Example 4: Convert 100 kj to kcal
- Multiply 100 by 0.239006.
- 100 × 0.239006 = 23.9006 kcal.
- Resulting energy is 23.9006 kcal.

Conversion Definitions
kj (kilojoule): A kilojoule is a unit of energy in the International System of Units (SI), equal to 1000 joules. It measures energy, work, or heat. Kilojoules are often used in science and nutrition to express the amount of energy released or consumed.
kcal (kilocalorie): A kilocalorie, also called a Calorie with a capital C, is a unit of energy commonly used to measure food energy. One kilocalorie equals 1000 calories and is defined as the amount of energy needed to raise the temperature of 1 kilogram of water by 1 degree Celsius.
Conversion FAQs
Why is the conversion factor between kj and kcal set to 0.239006?
The factor 0.239006 comes from the relationship between joules and calories. Since 1 calorie equals approximately 4.184 joules, converting kilojoules to kilocalories requires dividing by 4.184, resulting in about 0.239006 kcal per kj.
Can I use the conversion formula for very large or very small energy values?
Yes, the formula works for any energy amount in kj. However, for extremely large values, rounding errors might occur when displaying results, especially if you limit decimal places. For very small values, precision may also be affected depending on decimal accuracy.
Is it acceptable to round the kcal result to fewer decimals?
Rounding depends on the needed precision. For nutritional labels, often 2 decimals are sufficient, but scientific calculations may require more. Always consider the context to decide how many decimals to keep.
Are kilojoules and kilocalories interchangeable in food energy labeling?
Both units measure energy but are not interchangeable without conversion. Different countries may prefer kj or kcal. Understanding how to convert between them ensures accurate interpretation of food energy.
Does converting kj to kcal affect the energy content?
Converting units does not change the actual energy content, only expresses it differently. The energy remains the same; only the number changes according to the unit system used.
