## Introduction to eV and MeV

**eV to MeV Calculator:** Electron-volts (eV) and megaelectron-volts (MeV) are units of energy used in particle physics. One eV is the amount of kinetic energy gained by an electron when it accelerates through an electric potential difference of one volt. MeV, being one million eV, is a larger unit used to describe higher energy levels in subatomic particles.

## How to Use the eV to MeV Calculator

To convert energy from electron-volts (eV) to megaelectron-volts (MeV), simply enter the value in eV into the input box below and click the "Calculate" button. The result will be displayed in MeV. You can also clear the input using the "Clear" button to start a new calculation.

## Frequently Asked Questions (FAQs)

### What is an electron-volt (eV)?

An electron-volt (eV) is a unit of energy equal to approximately 1.602 Ã— 10^{-19} joules.

### What is a megaelectron-volt (MeV)?

A megaelectron-volt (MeV) is equal to one million electron-volts, used for describing higher energy levels in subatomic particles.

### How is eV related to MeV?

1 MeV is equal to 1,000,000 eV, so to convert eV to MeV, you divide the energy in eV by 1,000,000.

### Why use MeV instead of eV?

MeV is used when dealing with much larger energy levels, such as in nuclear reactions or high-energy physics.

### Can this calculator be used for other conversions?

No, this calculator is specifically designed for eV to MeV conversions.

### Is this calculator accurate?

Yes, this calculator provides accurate results based on the correct input values.

### What if I enter a non-numeric value?

The calculator only accepts numeric values, and non-numeric input will result in an error or no output.
