**About Specific Internal Energy Calculator (Formula)**

The Specific Internal Energy Calculator calculates a substance’s specific internal energy based on the substance’s total internal energy and mass. According to the definition of specific internal energy, it is defined as the amount of internal energy per unit mass of a substance, usually expressed in Joules per kilogram.

Calculating specific internal energy is simple and straightforward. It is represented by the symbol Es, and **it follows the following formula:**

**Es = TE / TM**

Where Es is the specific internal energy (J/kg), TE is the total internal energy (Joules), and TM is the total mass (kg) of the substance. The formula shows that the specific internal energy is directly proportional to the total internal energy and inversely proportional to the total mass.

By entering the total internal energy and mass values into the Specific Internal Energy Calculator, you can easily calculate a substance’s specific internal energy. The calculator then performs the necessary calculations and gives you the specific internal energy value in Joules per kilogram.

In the fields of thermodynamics, physics, and engineering, this tool is commonly used. In order to understand how substances behave and how they perform work, it is essential to calculate the specific internal energy quickly and accurately. By using this calculator, scientists and engineers can easily determine the specific internal energy of substances, and use that information to design and optimize systems and processes that involve energy transfer.
