Contrary to a prevalent opinion, the Metric System is easily mastered. A perfect acquaintance with the metric tables is, naturally, indispensable, and the abbreviations for the different weights and measures should be thoroughly at command. For the rest, the system is simply that of arithmetical decimals, requiring chiefly a correct use of the decimal point. Only a tyro would read .065 six and five-tenths hundredths instead of sixty-five thousandths; so Gm. .065 would never be read by one acquainted with decimals six centigrams and five milligrams, but sixty-five milligrams.
