We have made a precise measurement of the central inclusive jet cross section at $\sqrt{s}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1.8\mathrm{TeV}$. The measurement is based on an integrated luminosity of $92{\mathrm{pb}}^{\ensuremath{-}1}$ collected at the Fermilab Tevatron $\overline{p}p$ Collider with the D0 detector. The cross section, reported as a function of jet transverse energy $({E}_{T}\ensuremath{\ge}60\mathrm{GeV})$ in the pseudorapidity interval $|\ensuremath{\eta}|\ensuremath{\le}0.5$, is in good agreement with predictions from next-to-leading order quantum chromodynamics.
