eV to Volts Calculator
Convert between electronvolts (energy) and volts (electric potential) using the elementary charge constant
Elementary charge (e) = 1.602176634 × 10⁻¹⁹ Coulombs
Conversion Formula
Volts (V) = Electronvolts (eV) / Elementary charge (e)
Electronvolts (eV) = Volts (V) × Elementary charge (e)
Common Conversions
1 eV → Volts
1.0 eV = 1.0 V
100 eV → Volts
100.0 eV = 100.0 V
1 V → eV
1.0 V = 1.0 eV
5.5 V → eV
5.5 V = 5.5 eV
1 keV → Volts
1,000 eV = 1,000 V
0.001 eV → Volts
0.001 eV = 0.001 V
What is an Electronvolt (eV)?
An electronvolt (eV) is a unit of energy equal to the amount of energy gained or lost by a single electron when moving through an electric potential difference of one volt. Key facts:
- 1 eV = 1.602176634 × 10⁻¹⁹ Joules
- Used in atomic, nuclear, and particle physics
- Submultiples: meV, keV | Multiples: MeV, GeV
What is a Volt (V)?
A volt (V) is the SI unit of electric potential difference and electromotive force. Key facts:
- 1 V = 1 Joule per Coulomb (1 J/C)
- Named after physicist Alessandro Volta
- Measures the "push" in an electrical circuit
- Common in everyday electronics
Usage Tips & Notes
1 eV corresponds to 1 Volt for a single electron (practical conversion)
Use higher precision for scientific calculations
eV measures energy, Volts measure potential difference
For multiple electrons: Total eV = Voltage × Number of electrons
Common in semiconductor physics and particle accelerators
