摘要：

This paper presents the current status of the NIST SI watt experiment. Included are goals for the near future as well as projections regarding the viability of monitoring and/or replacing the kilogram mass standard. Although several significant systematic errors have yet to be evaluated, the standard deviation of the mean of our present measurement distributions is 0.05 ppm.
