    Abstract
    We determine the dielectron widths of the Upsilon(1S), Upsilon(2S), and Upsilon(3S) resonances with better than 2% precision by integrating the cross section of e(+)e(-)->Upsilon over the e(+)e(-) center-of-mass energy. Using e(+)e(-) energy scans of the Upsilon resonances at the Cornell Electron Storage Ring and measuring Upsilon production with the CLEO detector, we find dielectron widths of 1.252 +/- 0.004(sigma(stat))+/- 0.019(sigma(syst)) keV, 0.581 +/- 0.004 +/- 0.009 keV, and 0.413 +/- 0.004 +/- 0.006 keV for the Upsilon(1S), Upsilon(2S), and Upsilon(3S), respectively.
