2 ev equals approximately 3.204 x 10-19 coulombs.
This conversion takes the energy in electronvolts and translates it into electric charge in coulombs. Since 1 eV is the energy gained or lost by an electron moving through a potential difference of 1 volt, converting to coulombs involves considering the elementary charge. The calculation uses the fundamental charge value, making it possible to find how much charge corresponds to 2 eV.

Conversion Formula
The formula to convert electronvolts to coulombs involves multiplying the energy in ev by the elementary charge (approximately 1.602176634 x 10-19 coulombs). Because 1 eV is the energy of an electron moving through a 1-volt potential, the charge transferred is that energy divided by the voltage, which simplifies to multiplying by the elementary charge.
Mathematically, it looks like this: Charge (C) = Energy (eV) x Elementary Charge (C).
For example, converting 2 ev:
- Multiply 2 ev by 1.602176634 x 10-19 C.
- 2 x 1.602176634 x 10-19 = 3.204353268 x 10-19 C.
Conversion Example
Suppose you want to convert 5 ev into coulombs, here’s what you do:
- Take the energy value, which is 5 ev.
- Multiply 5 by 1.602176634 x 10-19 C.
- Result: 5 x 1.602176634 x 10-19 = 8.01088317 x 10-19 C.
- This means 5 ev is equivalent to approximately 8.0109 x 10-19 coulombs.

Conversion FAQs
How does energy in ev relate to electric charge in coulombs?
Energy in ev measures how much work an electron can do, while coulombs measure the amount of electric charge. The relation involves the elementary charge because each electronvolt corresponds to a specific charge transfer, calculated by multiplying ev by elementary charge.
Can I convert any energy in ev directly into coulombs?
Yes, but only when considering the charge associated with that energy, which involves multiplying the energy value by the elementary charge. This conversion assumes the energy is related to the movement of a single electron or a similar charge.
Why is the elementary charge used in converting ev to coulombs?
The elementary charge is the fundamental charge of a single electron, approximately 1.602176634 x 10-19 C. It links the energy in ev to actual charge by quantifying how much charge corresponds to a given amount of energy at atomic scales.
What are practical uses of converting ev to coulombs?
This conversion is used in physics and electronics to determine the amount of charge involved in atomic or subatomic processes, such as in particle physics experiments, semiconductor physics, or energy calculations in microscopic systems.
How accurate is the conversion from ev to coulombs?
The conversion is highly accurate because it relies on the precise value of the elementary charge. Minor variations are negligible for most scientific purposes, making it a reliable way to quantify charge from energy measurements.
