## About E = mc² Calculator

The **E = mc²** Calculator is based on Albert Einstein’s famous equation, which explains the equivalence of mass and energy. This formula demonstrates that a small amount of mass can be converted into a vast amount of energy, a principle fundamental to nuclear reactions and particle physics.

### Formula

The formula is:

**E = mc²**

Where:

**E**is the energy produced, measured in joules.**m**is the mass of the object, measured in kilograms.**c**is the speed of light in a vacuum, approximately 299,792,458 meters per second (m/s).

This equation shows that energy (E) is equal to the mass (m) of an object multiplied by the square of the speed of light (c²).

### How to Use

To use the E = mc² Calculator:

- Determine the mass of the object in kilograms.
- Multiply the mass by the speed of light squared (c²).
- The result will give you the energy (E) produced in joules.

This simple calculation demonstrates the immense energy contained within even small amounts of matter.

### Example

Suppose you have a mass of 1 kilogram. To find out how much energy this mass can produce:

**E = 1 kg × (299,792,458 m/s)² = 89,875,517,873,681,764 joules**

This means 1 kilogram of mass can be converted into approximately 90 trillion joules of energy.
