This book contains comprehensive reference material on the use of the International System of Units (SI system). It is now the world’s most widely used system of measurement, developed in 1960 from the metric system. As some countries, notably the United States and the United Kingdom, still continue to use customary units in addition to SI, this book also provides information on CGS, FPS and MKS systems of units.
The book is organized into 12 chapters. The first nine chapters acquaint the readers with the definitions of the base units in the SI system, application of prefixes, realization of derived and supplementary units, conversion factors, general physical data, and several examples to illustrate the use of conversion factors between the units used in different systems.
The book also contains engineering related data, in SI units, on properties of some metals, alloys and polymers for use by design engineers. Data on threaded fastners is also presented in SI units. Besides, there is miscellaneous other information, such as properties of gases, paper sizes, solar system, and earthquake severity measure-ment scale, presented in the context of the use of the SI system.
The book will be useful as a handy guide to students of science and engineering, technicians, scientists and engineers, as well as authors and editors of technical books.
