We live in a physical universe, and a complete system of standardised units describing the physical quantities around us is required to allow us to measure and quantify the universe and its contents. Without a standard unit system, trade would be impossible and the sciences would be unable to build on previous results.
This book collates information on the units of measurement in use, defining them and comparing to other units in the same and other systems.
