Dimensions on Dimensionless Wall Distance (y+)

Hopefully a quick question:
I am writing some scripts to back out some nice y+/u+ plots. I think I have a pretty good understanding of what y+ is, why it's important, so on and so forth.
My question is how I should handle the units on the friction velocity term. I realize that the y+ term should be analagous to Reynolds number (length * velocity / viscosity). However, the common treatment of the friction velocity is:
edit: Just realized that I'm simply missing a g_c.
