The Kilojoules to Calories Calculator
The Kilojoules to Calories Calculator is used to convert energy values from kilojoules (kJ) to various types of calories, including thermochemical calories, 15°C calories, and large/food calories. This is useful for comparing energy values in different measurement systems, particularly in fields like nutrition and chemistry.
Formula:
1. Thermochemical calories: 1 kJ = 239.0057 calth
E(calth) = E(kJ) × 239.0057
2. 15°C calories: 1 kJ = 238.9201 cal15
E(cal15) = E(kJ) × 238.9201
3. Large/Food calories: 1 kJ = 0.239 Cal
E(Cal) = E(kJ) × 0.239
How to use the Kilojoules to Calories Calculator:
1. Enter the energy value in kilojoules into the input box.
2. Select the type of calorie unit you wish to convert to.
3. Click on "Calculate " to convert the entered value to calories.
4. The result will be displayed in a table format.
5. Click on "Clear" to reset the input field.
