Abstract

The National Prototype (NP) of the Kilogram (No.57) is being maintained in NPL since 1957. The traceability is also maintained in mass measurements. The mass value of the NP is disseminated to lower grades of standards by sub-division method. In subdivision method series of weights are calibrated using with only one reference standard weight. In this paper a convenient method is described for calibration of multiple and sub-multiple of 1 kg. Suitable weighing designs, their solutions and also how to find uncertainties of measurement by Least Square Principle (LSP) are given in details.
