Hello- is it possible to convert MeV to V? If so, how is it done? For example if a particle is emmitted with an energy of 4.19MeV- how can this be changed into V? Any help is greatly appreciated.

Pengwuino said:They are not teh same unit of measure. eV is a unit of energy (1.602 x 10^19 ev = 1 Joule) and V is electrical potential. I think my intro to modern physics said its the energy required to move an electron through a 1 volt potential
Pengwuino said:Somehow...thinking if 1.602e^-19 J = 1eV then shouldn't 1.602e^19 eV = 1J... I have yet to do a homework problem or exam problem where i got the answer wrong... maybe its because i was rarely ever asked for an answer in Joules...
To convert MeV (megaelectronvolts) to V (volts), you can use the formula V = E/q, where E is the energy in MeV and q is the charge of the particle in coulombs. This formula is based on the relationship between energy and voltage, where one electronvolt is equal to one volt.
Converting MeV to V is necessary for many scientific and technological applications, especially in the fields of physics and engineering. It allows us to measure and express the energy of particles in terms of voltage, which is a more practical unit for many purposes.
No, there is no single conversion factor for MeV to V. As mentioned before, the conversion depends on the charge of the particle. For example, to convert MeV to V for an electron, you would use the charge of an electron (1.602 x 10^-19 C) in the formula V = E/q. For a proton, you would use the charge of a proton (1.602 x 10^-19 C).
Yes, you can use a calculator to perform the conversion. However, make sure to use the correct charge value for the specific particle you are working with. Also, be aware of any rounding errors that may occur.
Yes, there are many other units used to express energy, such as joules, kilowatt-hours, and ergs. However, MeV and V are commonly used in scientific and technological contexts, especially when dealing with subatomic particles and their interactions.
