1. What is Volt to Electron Volt Conversion?

The electron volt (eV) is a unit of energy equal to approximately 1.602×10⁻¹⁹ joules. In physics, when dealing with elementary charges, 1 volt is equivalent to 1 electron volt per elementary charge.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( eV \) — Energy in electron volts
• \( V \) — Voltage in volts

Explanation: For a single elementary charge (like one electron or proton), the energy in electron volts is numerically equal to the voltage.

3. Importance of the Conversion

Details: This conversion is fundamental in particle physics, electronics, and quantum mechanics where energies are often expressed in electron volts.

4. Using the Calculator

Tips: Simply enter the voltage in volts to get the equivalent energy in electron volts for a single elementary charge.

5. Frequently Asked Questions (FAQ)

Q1: Why is 1 volt equal to 1 electron volt?
A: By definition, 1 eV is the energy gained by a single electron moving through 1 volt of electric potential difference.

Q2: Does this conversion work for multiple charges?
A: For N elementary charges, the energy would be N × V electron volts.

Q3: What's the exact value of 1 eV in joules?
A: 1 eV = 1.602176634×10⁻¹⁹ joules (exact value as of 2019 SI redefinition).

Q4: Can I use this for macroscopic voltages?
A: While the calculation works mathematically, eV is typically used for atomic-scale phenomena.

Q5: How precise is this conversion?
A: The conversion is mathematically exact for single elementary charges.
