描述This book presents the practical aspects of mass measurements. Concepts of gravitational, inertial and conventional mass and details of the variation of acceleration of gravity are described. The Metric Convention and International Prototype Kilogram and BIPM standards are described. The effect of change of gravity on the indication of electronic balances is derived with respect of latitude, altitude and earth topography. The classification of weights by OIML is discussed. Maximum permissible errors in different categories of weights prescribed by national and international organizations are presented. Starting with the necessity of redefining the unit kilogram in terms of physical constants, various methods of defining the kilogram in terms of physical constants are described. The kilogram can be defined by Avogadro’s constant, ion collection of some heavy elements, levitation, voltage and Watt Balance. The detection of very small mass of the order of zeptogram through Nanotechnolgy is also discussed. Latest recommendations of CIPM are given.

Two-Pan Equal-Arm Balances, two bodies is commonly known as weighing process. The weighing is carried out through a balance. The balances can be broadly divided into two groups, namely (1) two-pan balance and (2) single-pan balance. In this chapter, we will consider two-pan, equal-arm balance.

Single-Pan Mechanical Balances,he beam is kept the same irrespective of the mass of the object weighed on it. It was a damped balance giving a constant indication in a short period. Because of the ease in getting mass of a body without much calculation, this type of balance became very popular in mid-fifties of twentieth century.

,Weights—Standards of Mass,t represent a body of known mass, so some people call it also as standard mass piece. Further as this body is used as reference for comparing mass of a body, it is called as standard of mass. Since long time the usage of the word weight is prevalent for a body of known mass. The weight is used to compare or determine the mass of another body.
