So, my physics final is tomorrow, and for the test we are given a list of constants. On this list is Planck's constant as 6.626x10^-34 J s. Now, that's all well and good, but they don't give it to us in eV s! And we need it in eV s for some of the problems. Given that we also get 1u=931.5MeV=1.66x10^-27kg, is there any way to convert it from J s to eV s? Thanks!
