1. What is AMU to MeV Conversion?

The AMU to MeV conversion calculates the energy equivalent of atomic mass units using Einstein's mass-energy equivalence principle. 1 atomic mass unit (AMU) is equivalent to approximately 931.494 mega electron volts (MeV).

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( \text{AMU} \) — Atomic mass units (unified atomic mass units)
• \( 931.494 \) — Conversion factor (MeV per AMU)

Explanation: This conversion is based on Einstein's equation E=mc², where mass can be converted to energy and vice versa.

3. Importance of Mass-Energy Conversion

Details: This conversion is fundamental in nuclear physics and chemistry, particularly in calculations involving nuclear binding energies, mass defects, and particle physics.

4. Using the Calculator

Tips: Enter the mass value in atomic mass units (AMU). The calculator will automatically compute the energy equivalent in mega electron volts (MeV).
