how do u convert eV to joules again?
Depends on the OP's intentions.If he's aiming to become a physicist (which may vey well not be the case),then it's a shame not to know THIS SPECIFIC CONVERSION...
I'm not talking about-psi->torr->pascals,but eV->J...

I think the most useful way to know this is realize that an eV is by defintion the work done moving an electron through one volt - i.e., since 1C * 1V = 1J, and the charge of an electron is 1.602x10^-19J...
Not true, and even if it were true, not relevant. Are you proposing that physics teaching standards can be lower because of the unlikelihood of producing physicists? Seems backwards to me.vincentchan said:99.99% students in a high school physics course are not going to be physicists, and,

It doesn't matter whether or not the electron was initially at rest.dextercioby said:One "eV" is the energy that an electron gets when accelerated from rest by a potential difference of 1V.

gonzolo said:A University I know has the same ratio. And that's not counting the significant amount of people who do not go to Univ. at all after school.

...says one in a 1000 students in college physics become physicists. So the question is : of the 20 who graduated, how many became physicists?
Or the energy lost by an already moving electron in passing through a potential difference of +1 volt; which is the work done by an electron moving through a potential of 1 volt, and that is pretty much what rachmaninoff said.dextercioby said:One "eV" is the energy that an electron gets when accelerated from rest by a potential difference of 1V.
The conversion factor for eV to joules is 1.602176634 × 10^-19 joules per eV.
To convert a specific energy value in eV to joules, you simply need to multiply the value in eV by the conversion factor of 1.602176634 × 10^-19.
eV (electron volts) is a unit of energy commonly used in atomic and nuclear physics, while joules is the standard unit of energy in the International System of Units (SI). Converting eV to joules allows for easier comparison and calculation of energy values in different systems.
No, the conversion factor for converting joules to eV is the inverse of the conversion factor for converting eV to joules. It is 6.241509074 × 10^18 eV per joule.
Yes, you can use an online conversion calculator or a physical conversion chart to quickly and accurately convert between eV and joules.
