This training manual is designed to introduce and assist naval personnel in the conversion from the English system of measurement to the metric system of measurement. The book tells what the "move to metrics" is all about, and details why the change to the metric system is necessary. Individual chapters are devoted to how the metric system will affect the average person, how the five basic units of the system work, and additional information on technical applications of metric measurement. The publication also contains conversion tables, a glossary of metric system terms, and guides to proper usage in spelling, punctuation, and pronunciation of the language of the metric system. (MP)
