To scientists and engineers, however, the answer is far from simple, and determining the answer demands consideration of an almost overwhelming number of factors. With an intriguing blend of history, fundamentals, and technical details, the Handbook of Mass Measurement sets forth the details

DOWNLOAD EBOOK →We learn about measurements in schools – It is just there in almost all topics of study- We also experience it in every walk of life. Even a child is born after a while -is a time measurement. Then the growth of the child is measured in weight and height, The school uniform is measured and tailored to suit the child. However, there is no specific focus given to this important topic and this book’s purpose is to present this topic as an easy guide and is illustrated with images and short snippets to make learning easy. This book covers Mass – the difference between mass and weight, speed, velocity, and acceleration- the book also covers other basic concepts like force, pressure, heat, and even a few health measurements. The author feels that the book will be useful and educative to all those willing to understand the system of measurements.

DOWNLOAD EBOOK →This report presents a collection of designs for the intercomparison of sets of weights for use in precision calibration of standards of mass. These include a number of previously unpublished designs which have an additional weight in each set to serve as the check standard for monitoring the performance of the weighing process. Also included are the classical designs of Benoit and Hayford. The complete least squares analysis is presented in integer form (i.e., with a common division) for the most widely used designs; and for the others, the standard deviations are given for various weight combinations when used as an ascending or as a descending series. Designs for sets of nominally equal objects, the 2 2 ... 1 1 ... series, the binary sequences, the 5 2 2 1 1 series, and the 5 3 2 1 1 and some miscellaneous series are given.

Accurate mass measurements are required for such purposes as: obtaining a known quantity of a sample for analysis ; preparation of analytical reagents ; and preparation of calibration standards. This document provides guidance on various important aspects of mass measurement as it is commonly carried out in alalytical laboratories." - page 1.

DOWNLOAD EBOOK →It is for the first time that the subject of quantities and their respective units is dealt this much in detail, a glimpse of units of measurements of base quantities of length, time, mass and volume is given for ancient India, three and four dimensional systems of measurement units are critically examined, establishment of the fact that only four base units are needed to describe a system of units, the basics to arrive at the unit of a derived quantity are explained, basic, derived and dimensionless quantities including quantity calculus are introduced, life history of scientists concerned with measurements units are presented to be inspiring to working metrologists and students. The International System of Units including, Metre Convention Treaty and its various organs including International National of Weights and Measure are described. The realisation of base units is given in detail. Classes of derived units within the SI, units permitted for time to come, units outside SI but used in special fields of measurements are described. Methods to express large numbers are explained in detail. Multiples and sub-multiples prefixes and their proper use are also given. The latest trends to redefine the base Kilogram, Ampere, Kelvin and Mole on existing base units of mass, electric current, temperature and amount of substance, in terms of a single parameter or fundamental constants are briefly described.
