Enter the total energy (J) and the total mass (g) into the Calculator. The calculator will evaluate the Joules Per Gram. 

Joules Per Gram Formula

JPG = E / m


  • JPG is the Joules Per Gram (Joules/g)
  • E is the total energy (J)
  • m is the total mass (g)

To calculate Joules Per Gram, divide the total energy by the mass.

How to Calculate Joules Per Gram?

The following steps outline how to calculate the Joules Per Gram.

  1. First, determine the total energy (J). 
  2. Next, determine the total mass (g). 
  3. Next, gather the formula from above = JPG = E / m.
  4. Finally, calculate the Joules Per Gram.
  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 (J) = 340

total mass (g) = 100
