The Mass-Energy Equivalence Calculator will calculate the:

- Energy obtained when an object with mass m is converted to energy and vice versa, that is mass obtained when a certain amount of energy is entirely converted to mass

**Calculation Parameters:** This calculator will calculate the Mass of object m or the Energy produced E based on the input of the variable being entered. Thus, if you want to calculate how much energy we obtain when converting an object into energy, we use the Mass of object variable for computation and the Energy produced variable as the calculated result.

Energy produced calculation |

E = m ∙ c^{2}E = ∙ ^{2}E = ∙ E = |

Mass of object calculation |

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

Mass Energy Equivalence Calculator Input Values / Results |

Speed of light (c) m/s [metre per second] |

Mass of object (m) kg [kilogram] |

Energy produced (E) J [Joule] |

Please note that the formula for each calculation along with detailed calculations are available below. As you enter the specific factors of each mass energy equivalence calculation, the Mass Energy Equivalence Calculator will automatically calculate the results and update the Physics formula elements with each element of the mass energy equivalence calculation. You can then email or print this mass energy equivalence calculation as required for later use.
