  Muon-electron conversion in nuclei is considered in the framework of the
Dualized Standard Model. The ratio $B_{\mu-e}$ of the conversion rate to the
total muon capture rate is derived, and computed for several nuclei in a
parameter-free calculation using parameters previously determined in different
physical contexts. The values obtained all lie within the present experimental
bounds, but some are so close as to seem readily accessible to experiments
already being planned. Similar considerations are applied also to muon-electron
conversion in muonium but give rates many orders of magnitude below the present
experiment limit.
