For the sake of clarity, let us summarize the canonical dimensions in natural units of various quantities:

$$\left[\, A_\mu{}^a(x)\, \right] \equiv [\, \mathbf{A}_\mu^{(\math... ..., ] \equiv [\, \mathbf{F}_{\mu\nu}{}^{(\mathrm{q})}\,]=( \mathrm{length} )^{-2}$$

$$[ \, g_0\, ]\equiv [ \, g\, ]=( \mathrm{length} )^0=1\ ,\qquad [\... ... ]= ( \mathrm{length} )^4 \ ,\qquad [\, \mu_0\, ]= ( \mathrm{length} )^{-2} \ .$$
