PROBLEMS IN IMPLEMENTING NEW MEASUREMENT UNIT DEFINITIONS OF THE SI USING FUNDAMENTAL CONSTANTS |

- Abstract:
- The paper is a digest of some problems to be considered should the proposed use of fundamental constants in the definition of measurement units of the SI be implemented: (a) more base units being multi-dimensional, instead of fixing the present problems in this respect; (b) the multidimensionality in the definitions; (c) how the magnitude of the base units is established; (d) the use of CODATA adjusted values of the constants for this specific purpose; (e) formal issues in stipulating algebraic expressions of the definitions, and in respect to the rounding or truncation of the numerical values; (f) formal issues with the use of the integer number NA; (g) limitations in new determinations that might arise from the stipulation of the values of several constants, for the CODATA to continue performing in future meaningful least squares adjustments of the fundamental constants taking into account future data; (h) implementation at the NMIs and Society level.
