Precision and uniformity are indispensable when working with physical quantities, units and formula symbols. Only through unambiguous and authoritative notation is interdisciplinary cooperation possible. The book gives an overview of all common quantities and units, which are needed in studies and teaching as well as in everyday work. All printed quantities and units are currently valid and standardized in ISO/IEC. The book includes: _brief introduction to the development of the system of units _overview on the system of quantities and units _calculating with quantity values _units (international system of units, SI) _notation of numbers _mathematical symbols _Standardized symbols for quantities (mechanics, space and time, radiation, solid state physics, etc.), elements, nuclides, particles and quantum states. _Appendix: conversion to the U.S. customary system of units.
