Einstein Mass Energy Calculator

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.
Einstein Mass Energy calculation
I want to calculate:
Mass: kg
Speed of Light in a Vacuum: m/s
Energy: J
Formula
Energy:
E = mc2

Mass:
m = E/c2

Speed of Light in a Vacuum:
c = √E/m

Where,
E = Energy,
m = Mass,
c = Speed of Light in a Vacuum.

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 = mc2
E = 25*52
E = 25*25
E = 625 J
Energy (E) = 625 J
