Dictionary of Units and Measures

This 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 S I. The units may be 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 alphabetically ordered list of units. There are NO units of currency.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 U K (Imperial) system with a statement on the implementation of 'metrication' in the U K, and the U S system.Finally there is a list of other sources concerned with the topic of measures and units (including other Web sites) and also some notes about this document.

The amount of information on this site is enormous. For those needing
information about a paricular unit of measure (no matter how obscure), this
should be the first place they visit.
