APPENDIX 



International Metric Systen.. In the international metric system the funda- 

 mental unit is the meter the anit of length. From this the units of capacity 

 (liter) and of weight (gram) were derived. All other units are the decimal 

 subdivisions or multiples of these. These three units are simply related 

 e.g., for all practical purposes 1 cubic decimeter equals 1 liter and 1 liter of 

 water weighs 1 kilogram. The metric tables are formed by combining the 

 words " meter," " gram," and " liter " with the six numerical prefixes, as in the 

 following tables : 



* One meter =39.37 inches; 1 liter =1.0567 liquid quarts; 1 gram =0.035 avoirdupois ounce. 



Units of Area. The table of areas is formed by squaring the length measures, 

 as in our common system. For land measure 10 meters square is called an 

 " are " (meaning " area "). The side of one are is about 33 feet. The hectare 

 is 100 meters square, and, as its name indicates, is 100 ares, or about 2 acres.
