# Special Theory of Relativity Formula

According to Einstein’s Theory, equivalent energy can be calculated using the mass(m) and the speed of light.

$$\begin{array}{l}E=mc^{2}\end{array}$$

Where,

• E is the equivalent energy
• m is the mass in kg
$$\begin{array}{l}c\cong 3\times 10^{8}m/s\end{array}$$

According to Einstein in Quantum fields which carry a certain amount of energy. In an empty space, the amount of energy gets larger as the fields get large. Hence, energy and mass are equivalent.
