Abstract : Electroweak precision measurements performed by CDF and DØ are reported, corresponding to data col- lected at the center-of-mass energy of 1.96 TeV with the integrated luminosity ranging from 0.75 fb^−1 to 4.9 fb^−1 . These include the measurement of the W boson charge asymmetry, the measurement of the Z boson rapidity distribution, the measurement of the Z boson p_T distri- bution, and direct measurement of the W boson mass and width.
