Enter the total energy (J) and the total mass (kg) into the Calculator. The calculator will evaluate the Energy Per Unit Mass.

## Energy Per Unit Mass Formula

EPM = E / M

Variables:

- EPM is the Energy Per Unit Mass (J/kg)
- E is the total energy (J)
- M is the total mass (kg)

To calculate Energy Per Unit Mass, divide the energy by the mass in kilograms.

## How to Calculate Energy Per Unit Mass?

The following steps outline how to calculate the Energy Per Unit Mass.

- First, determine the total energy (J).
- Next, determine the total mass (kg).
- Next, gather the formula from above = EPM = E / M.
- Finally, calculate the Energy Per Unit Mass.
- 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) = 700

total mass (kg) = 1000
