 A. METRIC TO ENGLISH. 



The standard of the metric system is the meter, which is the one ten-millionth part of a 

 meridian quadrant of the earth ; its one-tenth part is the decimeter, the cube of which is the 

 standard of capacity, the liter. The one one-hundredth part of the meter is the centimeter, and a 

 cubic centimeter of pure water at its maximum density (4 C.) gives the gram, the standard of weight. 

 Divisions of the standards are expressed by Latin prefixes, deci, centi, milli, while multiples are 

 expressed by Greek prefixes, deka, hecto, kilo, myria.

There are many other intermediate measures, and also square measures, but 

 they are le used, and their capacities may readily be calculated from those given. 



The ass med standard height of the mercury column at sea-level is 30 inches in English or 760 

 mm. in metn , The pressure of the mercury column (1 atmosphere) is approximately 1 5 lbs. (really 

 14/0' lbs.) to he square inch in English, and 1 kilogram (somewhat more) to the square centimeter in 

 metric.
