Enter the total energy (kJ) and the total time (days) into the Calculator. The calculator will evaluate the Kilojoules Per Day. 

Kilojoules Per Day Formula

KJD = E / T


  • KJD is the Kilojoules Per Day (kJ/day)
  • E is the total energy (kJ)
  • T is the total time (days)

To calculate Kilojoules Per Day, divide the energy in kilojoules by the time in days.

How to Calculate Kilojoules Per Day?

The following steps outline how to calculate the Kilojoules Per Day.

  1. First, determine the total energy (kJ). 
  2. Next, determine the total time (days). 
  3. Next, gather the formula from above = KJD = E / T.
  4. Finally, calculate the Kilojoules Per Day.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total energy (kJ) = 5000

total time (days) = 6
