Work on the redefinition of the kilogram and mole underway in many countries with experiments employing watt balances is analyzed. It is found that at present the reasons for the discrepancies in measurements of the Avogadro and Planck constants by different methods are not clear and that the required measurement accuracy has not been attained. Thus, studies with watt balances and crystalline silicon spheres must be continued in the framework of new projects.
