About KJtoCalories.com
KJtoCalories.com is an independent online conversion tool designed to help people easily convert kilojoules (kJ) to calories (kcal) and calories to kilojoules.
Our goal is to make energy values easier to understand, especially for people in Australia where food labels commonly display energy in kilojoules.
What We Provide
We provide:
- kJ to calorie conversions
- Calories to kJ conversions
- Conversion charts and common values
- Information about Australian food labels
- Australian food and restaurant calorie information
How We Calculate Conversions
Our calculators use the standard conversion:
1 kcal = 4.184 kJ
To convert kilojoules to calories:
Calories = kJ ÷ 4.184
To convert calories to kilojoules:
kJ = Calories × 4.184
We aim to keep our calculations accurate and clearly explain how each result is calculated.
Our Approach
We focus on simple, useful and easy-to-understand information. Nutritional information from food brands and restaurants should be checked against the latest official sources because product information can change.
KJtoCalories.com is an educational conversion website and is not a substitute for professional medical or dietary advice.
