Brightness-weighted differential source counts S2n(S) spanning the eight decades of flux density between 0.25{mu}Jy and 25Jy at 1.4GHz were measured from (1) the confusion brightness distribution in the MeerKAT DEEP2 image below 10{mu}Jy, (2) counts of DEEP2 sources between 10{mu}Jy and 2.5mJy, and (3) counts of NVSS sources stronger than 2.5mJy. We present our DEEP2 catalog of 1.7x10^4^ discrete sources complete above S=10{mu}Jy over {Omega}=1.04deg^2^. The brightness-weighted counts converge as S^2^n(S){propto}S^1/2^ below S=10{mu}Jy, so >99% of the {Delta}T_b_~0.06K sky brightness produced by active galactic nuclei and ~96% of the {Delta}T_b_~0.04K added by star-forming galaxies has been resolved into sources with S>=0.25{mu}Jy. The {Delta}T_b_~0.4K excess brightness measured by ARCADE 2 cannot be produced by faint sources smaller than ~50kpc if they cluster like galaxies.
