Solving the conversion of kilocalorie to kilojoule

To solve the conversion of kilocalorie to kilojoule, you need the base relationship. Since 1 kilocalorie equals 4.184 in kJ.

The formula to arrive at the answer is:

kJ=kcal×4,184mathrm{kJ} = mathrm{kcal} times 4{,}184

Step by step:

  1. Choose the numerical value that is in kcal.
  2. Set up the equation by substituting into the formula.
  3. To finish, you must multiply by the 4,184 value.

The final value will be your answer in kilojoule (kJ).

Example:

Learning to convert 1000 kcal to kJ is very easy when we use the 4,184 factor. The math is as follows: 1000 × 4,184 = 4184. With this, it becomes clear that 1000 kcal is the same thing as 4184 kJ.

1000 kcal=1000×4,184 kJ=4184 kJ1,000 text{ kcal } = 1,000 times 4{,}184 text{ kJ } = 4,184 text{ kJ }
