The Metric System has been adopted by Mexico, Brazil, Chile, Peru, etc., and except Russia and Great Britain, where it is permissive, by all European nations. Various names of the preceding systems are, however, frequently used: In Germany, 1/2 kilogram = 1 pound; in Switzerland, 2-10 of a metre = 1 foot, etc. If the first letters of the prefixes deka, hecto, kilo, myria, from the Greek, and deci, centi, mill, from the Latin, are used in preference to our plain English, 10, 100, etc., it is best to employ capital letters for the multiples and small letters for the subdivisions, to avoid ambiguities in abbreviations: 1 dekametre or 10 metres = 1 Dm.; 1 decimetre or 1-10 of a metre = 1 dm.

The Metre, unit of length, is nearly the ten-millionth part of a quadrant of a meridian, of the distance between equator and pole. The International Standard Metre is, practically, nothing else but a length defined by the distance between two lines on a platinum-iridium bar at 0° Centigrade, deposited at the International Bureau of Weights and Measures, Paris, France.

The Litre, unit of capacity, is derived from the weight of one kilogram pure water at greatest density, a cube whose edge is one-tenth of a metre and, therefore, the one-thousandth part of a metric ton.

The Gram, unit of weight, is a cube of pure water at greatest density, whose edge is one-hundredth of a metre, and, therefore, the one-thousandth part of a kilogram, and the one-millionth part of a metric ton.

One silver dollar weighs 25 grams, 1 dime = 2 1/2 grams, 1 five-cent nickel = 5 grams.

The Metric System was legalized in the United States on July 28, 1866, when Congress enacted as follows:

"The tables in the schedule hereto annexed shall be recognized in the construction of contracts, and in all legal proceedings, as establishin, in terms of the weights and measures now in use in the United States, the equivalents of the weights and measures expressed therein in terms of the metric system, and the tables may awfully be used for computing, determining, and expressing in customary weights and measures the weights and measures of the metric system." The following are tables of equivalents: i meter = 39.37 inches, i kilometer = .62137 mile. 1 sq. meter = 1.196 sq. yds. 1 cu. meter = 1.308 cu. yds. 1 Are = 119.6 sq. yds. 1 hectar = 2.471 acres. 1 liter = 1.0567 quarts. 1 hektoliter = 2.8375 bu. 1 ster = .2759 cord. 1 gram = 15.432 grains,

Troy. 1 kilogram = 2.2046 lb.

Avoir.

1 yd. = .9144 m. 1 rod = 5.029 m. 1 mile = 1.6093 Km. 1 sq. yd. = .8361 sq. m. 1 acre = 40.47 ares. 1 sq. mile = 259 Ha. 1 cubic foot = 28.317 liters. 1 cubic yard = .7645 cu. m. 1 liquid quart = .9465 liter. 1 bushel = .35243 HI. 1 lb. Troy = .37324 Kg. 1 lb. Avoir. = .4536 Kg.

The first column of equivalents gives the approximate legalized values, and contains most of the denominations in common use.
