1 Volt = 1 Joule /Coulomb

Joule and Coulomb are both derived units in the SI

In terms of SI base units
1 Joule = 1 kg m2 / s2

this comes from the formula for work done...
1 Joule = 1 N m
meter is already a SI base unit
and 1 Newton is kg m / s2
which comes from F=ma

1 Coulomb = 1 A s
straight from the definition of current as charge in Amps passing a point per unit time in seconds

once you've got Joule and Coulomb expressed in SI base units just got to divide the expressions for 1 Joule by 1 Coulomb
