    • Calories = Joules / 4.184
  • Calories to Joules: 1 Joule (J) = 0.239006 calories (cal)
    • To convert calories to Joules, multiply the energy in calories by 4.184:
    • Joules = Calories * 4.184
  • Kilojoules to Kilocalories: 1 Kilocalorie (kcal) = 4.184 Kilojoules (kJ)
    • To convert Kilojoules to Kilocalories, divide the energy in Kilojoules by 4.184:
    • Kilocalories = Kilojoules / 4.184
  • Kilocalories to Kilojoules: 1 Kilojoule (kJ) = 0.239006 Kilocalories (kcal)
    • To convert Kilocalories to Kilojoules, multiply the energy in Kilocalories by 4.184:
    • Kilojoules = Kilocalories * 4.184

These formulas are the backbone of any energy to calories conversion. Understanding them not only helps you appreciate how the calculator works but also allows you to perform manual conversions if needed.
