CDF and D0 have measured the effective leptonic weak mixing angle sin2T_lept_eff , using their full Tevatron datasets. I describe the techniques used in CDF and D0 analyses and the Tevatron combination of these two measurements. I also discuss the Zfitter standard model-based inference of the on-shell electroweak mixing angle sin2T_W(on-shell) , or equivalently, an indirect measurement of the W-boson mass. The combination of CDF and D0 results yields:

sin2T_lept_ eff = 0.23179 ± 0.00035,

sin2TW (on shell) = 0.22356 ± 0.00035

M_W (indirect) = 80.351 ± 0.018 GeV/c2. .
