Einstein's mass to energy converter formula -

$\text{Formula} : E = m * c^2$

Where 'E' is energy (in Joule), 'm' is mass (in kilograms) and c is the speed of light in vacuum (in meter/second).

Mass to Energy Calculator is an online tool for calculating values of the unknown parameters in the mass to energy converter formula provided other parameters are known.

## Step by Step Calculation

Step 1 :

Mass Energy Equivalence is the concept that any mass has an associated energy and vice versa.

Formula:

Energy :

E = mc2 .

Mass :

m = E / c2 .

Speed of light in a vacuum :

c = √(E / m) .

Step 2 :

State the equation you plan to use and plug in the values.

## Example Problems

1. ### The minimum energy of light rays that pass in the vaccum is 12.6 m/s and the energy is 45.7 J. Calculate the mass.

Step 1 :

Plug the values in the formula.

Mass :

m = E / c2 .

m = 45.7 / (12.6)2

m = 0.288 g

2. ### The minimum energy of light rays that pass in the vaccum is 3.6 m/s and the mass is 5.3 kg. Calculate the energy.

Step 1 :

The given:

Mass (m) = 5.3 Kg .

Energy (E) = ? J .

Spped of light in a vacuum = 3.6 m/s .

Step 2 :

Plug the values in the formula.

Energy :

E = mc2 .

E = 5.3 * (3.6)2
