Converting units from one type of usage to another is a constant and regular problem that engineers and scientists have to solve. This book will therefore be invaluable as it provides a complete coverage of all the conversion factors required. Covering areas such as mechanical units, thermal units, units of physical chemistry, units of light, units of electricity and magnetism and also radiation. References are given throughout and there is a comprehensive index.

This unique handbook enables readers to quickly and easily convert units--eliminating all the problems associated with conversion. It contains 62 charts, covering virtually every field of scientific endeavor based upon values by the foremost authoritative sources such as ANSI, IOS, and the IEEE. Written by the chairman of the CSA Technical Committee on the International System of Units. Includes an index.

The general purpose of this handbook is to prepare scientists, engineers, and technicians of the U.S. Army Materiel Development and Readiness Command (DARCOM) for increasing use of the International Systems of Units (SI) or, as it is frequently referred to, the "metric system." The specific objectives are to give DARCOM personnel (1) the tools required to convert the units of physical quantities and equations to SI units, (2) the information needed to correctly interpret specifications and documentation using the SI, and (3) the information needed to generate specifications and prepared documentation in SI units. Chapter 1 presents a paragraph outline of the handbook to facilitate its use, and a brief history of the introduction of and increasing use of the SI in the US. Definitions, rules, and conventions fundamental to the SI and its use are to be found in Chapters 2 and 3. Methods for converting non-SI units to SI units are given in Chapter 4. The methods make use of "unit equalities" and, if applied rigorously, will minimize or eliminate errors in unit conversions. A relatively simple method is presented for modifying equations such that equations derived for use with non-SI units can be used with SI units. Tables of unit equalities, experimentally determined constants expressed in SI units, and dimensionless quantities are given in Chapter 5. Chapter 6 is concerned with the use of SI in military engineering drawings, and covers dual dimensioning and conversion of the units of dimensions. Sample calculations illustrating methods of converting units and modifying equations are given in Chapter 7.

This invaluable reference manual provides well-organized tables of over 2100 conversion factors for measures ranging from time and length to metabolic rate and viscosity. An index defines each term: acres, dynes, joules, liters, knots, and so on. Also included are guides to abbreviations, to physical and technical dimensions, and to the système internationale (SI).

Metric Units and Conversion Charts A Metrication Handbook for Engineers, Technologists, and Scientists Second Edition Why waste your valuable time hunting for conversion factors, symbols, and units? With this handbook, you can convert from one measurement system to any other by means of 62 conversion charts covering almost every field of science. The charts are based on values published by the foremost authoritative sources such as the American National Standards Institute (ANSI), the International Organization for Standardization (ISO), and the Institute of Electrical and Electronics Engineers, Inc. (IEEE). The charts are universal, and so conversions can be made quickly and confidently. This much-expanded second edition has the following features: * The charts make a clear distinction between SI and other metric units by identifying SI units by red boxes. * Official symbols of all SI units are given, along with the name of the unit. * The recommended symbols for quantities are shown at the top of each chart. * A new chapter on mass, force and gravity explains how the units of force were established. * For introductory courses, chapters are included explaining quantity equations and numerical equations, together with worked-out examples. * For classroom work, over 100 review questions, together with answers.

Mankind has a fascination with measurement. Down the centuries we have produced a plethora of incompatible and duplicatory systems for measuring everything from the width of an Egyptian pyramid to the concentration of radioactivity near a nuclear reactor and the value of the fine structure constant. With the introduction first of the metric system and of its successor the Système International d'Unités (SI), the scientific community has established a standard method of measurement based on only seven core units. The Encyclopaedia of Scientific Units, Weights and Measures converts the huge variety of units from all over the world in every period of recorded history into units of the SI. Featuring: - An A - Z of conversion tables for over 10,000 units of measurements. - Tables of the fundamental constants of nature with their units. - Listings of professional societies, and national standardization bodies for easy reference. - An extensive bibliography detailing further reading on the multifarious aspects of measurement and its units. This huge work is simply a "must have" for any reference library frequented by scientists of any discipline or by those with historical interests in units of measurement such as archaeologists.
