Conversion Formula:
| From: | To: |
The electron volt (eV) to volts conversion calculates the equivalent voltage based on the energy in electron volts. One electron volt is defined as the amount of kinetic energy gained by a single electron accelerating from rest through an electric potential difference of one volt.
The calculator uses the conversion formula:
Where:
Explanation: This conversion relates energy in electron volts to the equivalent voltage that would give an electron that amount of energy.
Details: This conversion is essential in particle physics, semiconductor physics, and electronics where energies are often expressed in electron volts but need to be related to practical voltage measurements.
Tips: Enter the energy value in electron volts (eV). The value must be positive and greater than zero.
Q1: What is an electron volt?
A: An electron volt is a unit of energy equal to approximately 1.602 × 10⁻¹⁹ joules, defined as the amount of kinetic energy gained by a single electron accelerating through one volt of electric potential difference.
Q2: Why is the conversion factor so small?
A: The conversion factor is small because an electron volt represents the energy of just one electron, while a volt is a much larger unit of electric potential.
Q3: In what fields is this conversion commonly used?
A: This conversion is commonly used in particle physics, accelerator physics, semiconductor device physics, and electron microscopy.
Q4: Can I convert volts back to electron volts?
A: Yes, to convert volts back to electron volts, you would multiply the voltage by the elementary charge (eV = V × e).
Q5: Is the elementary charge value exact?
A: The elementary charge is a fundamental physical constant with a defined value of approximately 1.60217662 × 10⁻¹⁹ coulombs, though it may be rounded differently in various contexts.
