1. What is the AMU to MeV Equation?

The AMU to MeV equation converts atomic mass units to their energy equivalent in mega electron volts using Einstein's mass-energy equivalence principle. This conversion is fundamental in nuclear physics and particle physics.

2. How Does the Calculator Work?

The calculator uses the equation:

Where:

• \( \text{AMU} \) — Atomic mass unit (1/12th the mass of a carbon-12 atom)
• \( 931.494 \) — Conversion factor (MeV per AMU)

Explanation: This conversion factor comes from Einstein's E=mc², where 1 AMU is equivalent to approximately 931.494 MeV.

3. Importance of Mass-Energy Conversion

Details: This conversion is crucial in nuclear reactions where mass is converted to energy (and vice versa), such as in nuclear power generation, nuclear weapons, and particle physics experiments.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 931.494 MeV/AMU?
A: This value comes from the precise measurement of the mass of nucleons and the speed of light squared (E=mc²).

Q2: Is this conversion exact?
A: The factor 931.494 is an approximation. More precise calculations may use 931.494061(21) MeV/c² per AMU.

Q3: Can this be used for any mass?
A: Yes, any mass in AMU can be converted to its energy equivalent in MeV using this equation.

Q4: How is this related to nuclear binding energy?
A: The mass defect (difference between nuclear mass and sum of nucleon masses) converted to MeV shows binding energy.

Q5: What's the energy equivalent of 1 AMU in joules?
A: 1 AMU ≈ 1.49242×10⁻¹⁰ joules (using 1 MeV = 1.60218×10⁻¹³ J).
