The inclusive cross sections times leptonic branching ratios for $W$ and $Z$ boson production in $p\overline{p}$ collisions at $\sqrt{s}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1.8$ TeV were measured using the D0 detector at the Fermilab Tevatron collider: ${\ensuremath{\sigma}}_{W}B(W\ensuremath{\rightarrow}e\ensuremath{\nu})\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}2.36\ifmmode\pm\else\textpm\fi{}0.07\ifmmode\pm\else\textpm\fi{}0.13\mathrm{nb}$, ${\ensuremath{\sigma}}_{W}B\left(W\ensuremath{\rightarrow}\ensuremath{\mu}\ensuremath{\nu}\right)\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}2.09\ifmmode\pm\else\textpm\fi{}0.23\ifmmode\pm\else\textpm\fi{}0.11\mathrm{nb}$, ${\ensuremath{\sigma}}_{Z}B\left(Z\ensuremath{\rightarrow}{e}^{+}{e}^{\ensuremath{-}}\right)\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0.218\ifmmode\pm\else\textpm\fi{}0.011\ifmmode\pm\else\textpm\fi{}0.012\mathrm{nb}$, and ${\ensuremath{\sigma}}_{Z}B\left(Z\ensuremath{\rightarrow}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}\right)\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0.178\ifmmode\pm\else\textpm\fi{}0.030\ifmmode\pm\else\textpm\fi{}0.009\mathrm{nb}$. The first error is the combined statistical and systematic uncertainty, and the second reflects the uncertainty in the luminosity. For the combined electron and muon analyses we find ${\ensuremath{\sigma}}_{W}B(W\ensuremath{\rightarrow}l\ensuremath{\nu})/{\ensuremath{\sigma}}_{Z}B(Z\ensuremath{\rightarrow}{l}^{+}{l}^{\ensuremath{-}})\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}10.90\ifmmode\pm\else\textpm\fi{}0.49$. Assuming standard model couplings, this result is used to determine the width of the $W$ boson, $\ensuremath{\gamma}(W)\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}2.044\ifmmode\pm\else\textpm\fi{}0.093\mathrm{GeV}$.
