Some fundamental concepts of units, dimensions, and physical measurements are discussed, and illustrations of the misunderstandings that exist in the literature concerning these concepts are given. The differences between measure and physical equations are outlined, and a simple example is considered. The choice of how many and which units to use as basic is shown to be completely arbitrary, and the choice is usually made to produce maximum accuracy and convenience. Various mechanical, thermal, and electrical systems of units in common use today are presented, and an engineering (ft-lbf-ampsec) system is developed to describe electromagnetic problems. The history of some important physical units is traced, and the latest definitions of these units are used to obtain convenient conversion tables for various physical quantities.
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.

Prealgebra 2e is designed to meet scope and sequence requirements for a one-semester prealgebra course. The text introduces the fundamental concepts of algebra while addressing the needs of students with diverse backgrounds and learning styles. Each topic builds upon previously developed material to demonstrate the cohesiveness and structure of mathematics. Students who are taking basic mathematics and prealgebra classes in college present a unique set of challenges. Many students in these classes have been unsuccessful in their prior math classes. They may think they know some math, but their core knowledge is full of holes. Furthermore, these students need to learn much more than the course content. They need to learn study skills, time management, and how to deal with math anxiety. Some students lack basic reading and arithmetic skills. The organization of Prealgebra makes it easy to adapt the book to suit a variety of course syllabi.
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.
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).
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.
