found either by looking under the category in which they are
used [such as length, mass, density, energy etc.], or else
by picking one unit from an alpabetically ordered list of
units. There is an outline of the S.I.; a list of its basic
defining standards and also some of its derived units; then
another list of all the S.I. prefixes and some notes on
conventions of usage. There is a short historical note on
measures generally; descriptions of the metric system, the

of 'metrication' in the UK, and the U.S. system. Finally
