## Formula

Energy:

**E = mc ^{2}**

Mass:

**m = E/c ^{2}**

Speed of Light in a Vacuum:

**c = √E/m**

**Where,**

E = Energy,

m = Mass,

c = Speed of Light in a Vacuum.

Einstein Mass Energy law states the principle that mass (m) and energy (E) are equivalent according to the equation E = mc2, where c is the velocity of light. When energy is removed from a system then mass is always removed along with the energy.

This advanced online Einstein Mass Energy Calculation is used to calculate and find the Energy (E), Mass (M) and Speed of Light in a Vacuum for the given details.

**Example:**

Calculate the Einstein Mass energy for the given details.

Mass (m) = 25 kg

Speed of Light in a Vacuum(c) = 5 m/s

**Solution:**

**Apply formula:**

E = mc^{2}

E = 25*52

E = 25*25

E = 625 J

**Energy (E) = 625 J**
