2000 kilojoules (kj) is equal to approximately 478.924 calories.
This conversion is done by multiplying the energy value in kilojoules by the factor that converts kilojoules to calories. Since 1 kilojoule equals 0.239006 calories, 2000 kj is converted by multiplying 2000 by this number to get the calorie equivalent.

Conversion Formula
The formula to convert kilojoules (kj) to calories is based on the energy equivalence between the two units. 1 kilojoule equals approximately 0.239006 calories. So, to convert kj to calories, multiply the kilojoule value by 0.239006.
Formula:
calories = kilojoules × 0.239006
Why it works: Kilojoule and calorie both measure energy but in different scales. Kilojoule is part of SI units while calorie is a traditional unit. The conversion factor comes from how much energy each unit represents.
Example: Convert 2000 kj to calories.
- Step 1: Identify the conversion factor: 0.239006
- Step 2: Multiply 2000 by 0.239006
- Step 3: 2000 × 0.239006 = 478.012 calories
Note: Some sources round the factor slightly differently, so you may see small variations.
Conversion Example
- Convert 1500 kj to calories:
- Multiply 1500 by 0.239006
- 1500 × 0.239006 = 358.509 calories
- The result is about 358.509 calories.
- Convert 500 kj to calories:
- 500 × 0.239006 = 119.503 calories
- This means 500 kj equals roughly 119.503 calories.
- Convert 3000 kj to calories:
- 3000 × 0.239006 = 717.018 calories
- So, 3000 kj converts to approximately 717.018 calories.
- Convert 750 kj to calories:
- 750 × 0.239006 = 179.2545 calories
- Therefore, 750 kj is about 179.2545 calories.
- Convert 100 kj to calories:
- 100 × 0.239006 = 23.9006 calories
- This shows 100 kj equals almost 23.9006 calories.

Conversion Definitions
Kilojoule (kj): A kilojoule is a unit of energy in the International System of Units. It equals 1000 joules and measures the amount of work done or heat produced. Kilojoules are commonly used to express energy content in food and fuel.
Calories: Calories measure energy, especially in food energy content. One calorie is the energy needed to raise the temperature of 1 gram of water by 1 degree Celsius. In nutrition, the term calorie often means kilocalorie, which is 1000 actual calories.
Conversion FAQs
Why is the kilojoule to calorie conversion factor not a whole number?
The factor is derived from scientific measurement of energy units. Because a calorie and a joule measure energy differently, their relationship is a precise decimal, reflecting physical constants. Therefore, the conversion factor is about 0.239006, not a simple integer.
Can I convert calories back to kilojoules?
Yes, to convert calories to kilojoules, divide the calorie value by 0.239006 or multiply by approximately 4.184. This reverses the conversion, letting you switch between units depending on what’s needed.
Are these conversion values exact or approximate?
They are scientifically accurate but often rounded for simplicity. The factor 0.239006 is precise, but displayed numbers might be rounded, causing slight differences in results.
Why do nutrition labels sometimes show both kj and calories?
Different regions use different energy units. Kj is the SI unit, common in many countries, while calories are more familiar in places like the US. Showing both helps consumers understand energy content regardless of their preferred system.
Is there a difference between calorie and Calorie with a capital C?
Yes, in nutrition, a capital ‘Calorie’ means a kilocalorie (1000 small calories). This can cause confusion, but usually ‘Calories’ on food labels are actually kilocalories, equivalent to 4184 joules or 4.184 kj.
