SI Metric-Matters is promoting the use of International units with the correct names and symbols. Philip Bladon, from Worcestershire, in the United Kingdom, has compiled A Dictionary Of International Units. His book is filled with official SI units, 'Le Système International d' Unités', designated SI in all languages.

This book not only provides an excellent reference source for science students throughout their careers; it's also a fascinating book for trivia buffs and a delight for enthusiasts of the board game Scrabble®.  When you buy a copy you will soon enrich your vocabulary and discover unusual prefixes.  In addition to familiar prefixes like 'kilo' and  'milli'  there are eighteen more that can be used for multiples and submultiples of SI units.

With this dictionary, teachers can help promote the correct metric names and symbols and give guidance on how to write numerical values correctly. And it's not just in High schools and Secondary schools where this book is being used; Primary, and Junior school teachers around the world are finding it useful.
