  • Abstract
    The electronic realization of the kilogram project using the new NIST watt balance has been fully operational on a daily basis for several months. Short-term noise is at an all time low with overnight runs exhibiting standard deviations of parts in 108. With the exception of the mass standard, each standard reference has been calibrated with an uncertainty below a part in 108. Recent improvements that have led to the enhanced performance and current results are discussed
