## Mass Energy Calculator :

Enter the mass energy calculator its calculate the Mass in kilograms(kg), Energy in megajoules(MJ), and you get the calculation below the calculator check it.

## Mass Energy Formula :

Mass Energy Formula is equivalent energy E_{(m/s)} in meter per second is equal to the m _{(kg)} in kilogram and multiply the square of speed of light c^{2}_{(m/s)} in meter per second. Hence the Mass of Energy Formula can be written as,

**E _{(m/s)}=m _{(kg)} *c^{2}_{(m/s)}**

Where,

E→ equivalent energy in m/s

m→ mass in kg

c→ speed of light in m/s

c≅3*10^{8}m/s

## Sample Problems :

## Problem1 :

Calculate the mass m=2kg and speed of light c is the constant value solve according to the According to Einstein’s Theory

### Solution :

m=2kg

c≅3*10^{8}m/s

According to Einstein’s Theory,

E=mc^{2}

E=2*(3*10^{8}*3*10^{8})

E=1.8*10^{17} m/s

## Problem2 :

Calculate the mass m=6kg and speed of light c is the constant value solve according to the According to Einstein’s Theory

### Solution :

m=6kg

c≅3*10^{8}m/s

According to Einstein’s Theory,

E=mc^{2}

E=2*(6*10^{8}*6*10^{8})

E=7.2*10^{17} m/s
