【简介】
     A Dictionary of Units provides a summary of most of the units of measurement to be found in use around the world today (and a few of historical interest), together with the appropriate conversion factors needed to change them into a 'standard' unit of the SI.

The units may be found either by looking under the category in which they are used, (length energy etc.) or by picking one unit from an alphabetically ordered list of units. There is a Summary Table of the most often required Conversion Factors. There are NO units of currency. There is an outline of the SI system, a list of its 7 basic definitions, some of its derived units, together with a list of all the SI prefixes, and some of the rules and conventions for its usage. On the subject of measures generally, there is a short historical note. Then there are descriptions of the Metric system,and the UK (Imperial) system, followed by statements on the implementation of 'metrication' in the UK, and then the US system of measures.

At the bottom of this webpage is a list of other sources, and also some links to other Web sites. Finally there are some notes on this material.
