Homework Statement
How can i convert V to eV in a problem?
I know that 1V=1.6X10^-19 J but I don't see how that can help...
Thanks.

V is voltage (potential difference), but eV is energy …
1 eV is the https://www.physicsforums.com/library.php?do=view_item&itemid=75" (ie energy) when an electron (whose charge you can look up ) moves through a potential difference of 1 V.
lha08 said:So in this case, the charge of an electron is 1.60X10^-19 J...so is it impossible to convert eV to V? Not really sure...Thanks..

The conversion factor from volts (V) to electron volts (eV) is 1 eV = 1.602 x 10^-19 J.
To convert from volts to electron volts, simply multiply the value in V by the conversion factor of 1.602 x 10^-19.
No, this guide specifically focuses on converting volts to electron volts. For conversions between other units of energy, you will need to use different conversion factors.
Electron volts are a more convenient unit of measurement for small-scale energy interactions, such as those that occur in atomic and molecular systems. Converting from volts to electron volts allows for easier calculation and comparison of these energies.
One common mistake is forgetting to use the conversion factor of 1.602 x 10^-19. Another is mixing up the units and converting from eV to V instead of the other way around. It is important to double check your calculations and units to ensure an accurate conversion.
