After the 1973 report on the fundamental constants by Cohen and Taylor, a new measurement of Avogadro's constant, (N sub A), was published by Deslattes et al. Based on improved techniques, the result is considerably more precise than the 1973 value, which was based primarily on other types of data, and is 8.2 ppm (1.6 times the 1973 standard deviation) larger. In the present report, a new least-squares adjustment is made, with six parameters and using the measurement of (N sub A) plus other new data. Recommended values of 75 constants are presented, half of which differ from the former values by 1.0 to 1.5 times the 1973 standard deviation. The uncertainties of the new values are often much less than the 1973 uncertainties, 0.38 as large according to one figure of merit.

This volume contains original, refereed contributions by researchers from national metrology institutes, universities and laboratories across the world involved in metrology and testing. The volume has been produced by the International Measurement Confederation Technical Committee 21, Mathematical Tools for Measurements and is the twelfth in the series. The papers cover topics in numerical analysis and computational tools, statistical inference, regression, calibration and metrological traceability, computer science and data provenance, and describe applications in a wide range of application domains. This volume is useful to all researchers, engineers and practitioners who need to characterize the capabilities of measurement systems and evaluate measurement data. It will also be of interest to scientists and engineers concerned with the reliability, trustworthiness and reproducibility of data and data analytics in data-driven systems in engineering, environmental and life sciences.
