The necessity of defining the kilogram in terms of physical constants was already underscored in the first edition. However, the kilogram can also be defined in terms of Avogadro’s number, using a collection of ions of heavy elements, by the levitation method, or using voltage and watt balances. The book also addresses the concepts of gravitational, inertial and conventional mass, and describes in detail the variation of acceleration due to gravity. Further topics covered in this second edition include: the effect of gravity variations on the reading of electronic balances derived with respect to latitude, altitude and earth topography; the classification of weights by the OIML; and maximum permissible error in different categories of weights prescribed by national and international organizations. The book also discusses group weighing techniques and the use of nanotechnology for the detection of mass differences as small as 10-24 g. Last but not least, readers will find details on the XRCD method for defining the kilogram in terms of Planck’s constant.Springer Series in Materials Science,0933-033X ;155Physical measurementsMeasurement   Materials scienceMechanicsMechanics, AppliedMeasurement Science and Instrumentationhttps://scigraph.springernature.com/ontologies/product-market-codes/P31040Characterization and Evaluation of Materialshttps://scigraph.springernature.com/ontologies/product-market-codes/Z17000Theoretical and Applied Mechanicshttps://scigraph.springernature.com/ontologies/product-market-codes/T15001Physical measurements.Measurement   .Materials science.Mechanics.Mechanics, Applied.Measurement Science and Instrumentation.Characterization and Evaluation of Materials.Theoretical and Applied Mechanics.389.1015195Gupta S.
