Question about Converting Units

Postby AChoudhry_1L » Thu Oct 31, 2019 6:40 pm

How do we convert keV to joules? This was needed for homework problem 5 from section 1B.

1 eV = 1.60e-19 J, so convert from keV to eV to joules (dimensional analysis is easiest).

1keV = 1000 eV
1 eV = 1.60e-19 J

so 1keV = 1000 x 1.60e-19 J

the conversion from eV to J should be given on the test I think
