1 eV = 1.602176487(40)×10−19 joules from wikipedia.
J = jouleseV = electron volts1 J = 1.602 x 10-19 eVTo convert from J to eV, multiply the given value by 1.602 x 10-19To convert from eV to J, divide the given value by 1.602 x 10-19Example3 J to eV3 x 1.602 x 10-19 = 4.806 x 10-19 eV30 eV to J30 / 1.602 x 10-19 = 1.873 x 1020 J
The energy is 2,5116.10-18 J or 13,429 eV.
Energy(Joules)/Electron charge= Energy(eV) Therefore Divide by 1.6 x 10-19
One electron volt (eV) is equal to 1.60218 E (-19) joules. Therefore, 9.0 eV is equal to 1.44196 E (-18) joules.
Energy = hc/w= .2E-24/400E-9 = .5E-18 joules x 6.25E18 ev/J=3.125 ev.
Multiply by avagardoes number
