on the basis of the concensus below i feel very ignorant of what a charge is. Ithough a charge is energy. well I was wrong its a coulomb what ever that is.

The Farad is the unit of capacitance, but it does not have the unit of distance.

q = CV where q is charge, C is capacitance, and V is voltage.

C = q/V q is expressed in Coulombs and V is Joules/Couloumb

so the units of capacitance are:

1F = Col/(J/Col) = Col/1 x Col/J = Col^2/J

Couloumb is a fundamental unit like the meter or second.

1F = Col^2/N-m probably about as far as you want to take it, but you see it does not have units of distance.

The basic unit of capacitance is the Farad. A capacitor has a capacitance of 1F when a charge of 1 Volt across the capacitor produces a current of 1 Ampere through it. I hope that clears your doubt
