# E MC Squared Calculator Online

The E=mc² calculator is a powerful tool used to compute the amount of energy released or required for a given mass, as per Albert Einstein’s famous mass-energy equivalence formula: E = m * c².

### Formula of E MC Squared Calculator

E = m * c²

Where:

• E: Energy in joules (J).
• m: Mass in kilograms (kg).
• c: Speed of light in a vacuum, approximately equal to 299,792,458 meters per second (m/s).

This calculation illustrates the relationship between mass and energy, showing that a small amount of mass can be convert into a significant amount of energy, as detailed by Einstein’s theory of relativity.

## Table of General Terms

This table provides pre-calculated values for mass-to-energy conversions, aiding users to quickly access approximate energy equivalents without performing the calculation each time.

## Example of E MC Squared Calculator

Suppose we have a mass of 2 kilograms. To calculate the energy equivalent using the E=mc² formula:

• m = 2 kg
• c = 299,792,458 m/s

Plugging these values into the formula:

• E = 2 * (299,792,458)^2
• E = 1.797510358e17 joules

This result indicates that a mass of 2 kilograms has an energy equivalent of approximately 1.797510358e17 joules.
