- What Are the Units of q in the EField Equation?

Quick and possibly stupid question, but in the equation for calculating the electric field:

##{\mathbf E} = \frac{1}{4πe_0}\frac{q}{r^2} \hat {\mathbf r}##

What unit is ##q## in? Coulombs?

Although now that I think more on it I suppose it also depends on the units you're using to calculate the electric force on a charged particle, correct?
