EV to Volts Calculator
Calculate electric vehicle battery voltage by multiplying the number of cells by nominal cell voltage. Essential tool for EV battery management.

Quick Intro: Convert EV to Volts
Electron-volts (eV) and volts (V) are both key concepts in electrical physics. While eV measures energy, volts refer to electric potential. You can convert eV to V by dividing energy by the charge. For example, if you have 1 eV and a charge of 1.602×10⁻¹⁹ C (elementary charge), the potential difference is 1 volt. This calculator simplifies that process for practical uses like electronics, circuits, or quantum mechanics.
Formula to Convert EV to Volts
Formula 1 (using charge in C):Volts (V) = eV / Q
where Q is charge in coulombs.
Formula 2 (using elementary charge):Volts (V) = eV / (n × e)
where n = number of electrons, e = 1.602×10⁻¹⁹ C.
These formulas apply when calculating electrical potential from energy and charge.

Frequently Asked Questions - EV to Volts Calculator:
What is an electron-volt (eV)?
An eV is a unit of energy equal to 1.602×10⁻¹⁹ joules.
How do I convert eV to volts?
Use V = eV ÷ charge (in coulombs).
What is the value of elementary charge (e)?
The elementary charge e = 1.602×10⁻¹⁹ coulombs.
Can eV be directly converted to volts?
Yes, when charge is 1 elementary charge, volts = eV ÷ e.
Is eV a unit of voltage?
No, eV is a unit of energy, not voltage.
How does charge affect conversion?
More charge reduces voltage for the same energy (V = E/Q).
What does 1 eV represent?
It’s the energy gained by 1 electron across 1 volt.
Where is eV used?
In physics, electronics, quantum mechanics, and particle science.
Is negative eV possible?
Yes, it can indicate energy loss in physics contexts.
