Determine the threshold frequency of a metal with a work function of 7V

2. Relevant equations

Threshold frequency 'f'=W/h where w=work function, h=planck's constant

3. The attempt at a solution

This is such an easy question, but I am hung up on how to treat a work function that is expressed in volts seeming as the equation used to calculate the frequency requires it to be in joules I believe. I understand that volts can be expressed as joules per coulomb, but what would I do about the coulombs then?
