METRIC SYSTEM. 393 METRIC SYSTEM. mints, in oertain Oovfiniiiont. ])ul)lifations, in tlif Pliarmacopceia and the Dispensatory, in cer- tain measurements of the Coast and Geodetic Sur- vey, and in much of the work of the arts and sciences. The basal units of the metric system are: for length the meter, for small surfaces the square meter, for area of land the square dekameter (or are), for volume the cubic meter, for capacity the liter, for weight the gram, and ioy the monetary system the franc. The scale selected for the multiples and subdivisions of the various units is 10. The prefixes used to designate the nuiltiples of the measuring unit are deka (10), hekto (100), kilo (1000). and myria (10.000), all from the Greek, and those used to designate ■iuhdivisions are deci (0.1), ocnti (0.01), and niilli (0.001), from the Latin. Tlie ratio between the successive denomination.? in the system of linear measure, of weight, of capacity,' and of money is 10, the ratio between the successive denominations of surface measure is 100. and that of cubic measure is 1000. The unit of capacity, the liter, is equal to a cubic decimeter, and approximately so to the volume of a kilogram of water at the maximum density. Its equivalent Is 1.05671 liquid quarts (U. S. standard), or .88030 liquid quart (British). The unit of weight, the gram, is the mass weight of one cubic centimeter of water, standard pure, at the maximum density. Its equivalent in the English system is 1.5. 4.32 -f troy grains.
