CHAP. CCCI.-An Act to authorize the Use of the Metric System of Weights and Measures. Be it enacted, &c., That from and after the passage of this act it shall be lawful throughout the United States of America to employ the weights and measures of the metric system; and no contract or dealing, or pleading in any court, shall be deemed invalid or liable to objection because the weights or measures expressed or referred to therein are weights or measures of the metric system, SECTION 2. That the tables in the schedule hereto annexed shall be recog nized in the construction of contracts, and in all legal proceedings, as establishing, 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 said tables may be lawfully used for computing, determining, and expressing in customary weights and measures the weights and measures of the metric system. APPROVED July 28, 1866. Reproduced in Revised Statutes, sections 3569-70. Where weights, &c., of the metric system are used in invoices, the above equivalents must in all cases be applied. (S. S., 2362.) FRENCH LITRE S, REDUCED TO WINE-QUARTS. Litre 1.0567 Quart; Decilitre 10567 Quart. According to Act of July 28th, 1866. To reduce Lineal Metres, Aunes, and Berlin Ells to Lineal yards, proceed as follows: Metres, by adding to their number, 12, 10, and of; Aunes, by adding to their number 4, or 25 per cent. thereof; and Berlin Ells,* by multiplying their number by .7294, or by .73, which is sufficiently accurate for ordinary purposes. To reduce the lineal yards thus obtained to square yards, the above table may, of course, be used as in other cases. Ells of Brabant by multiplying their number by .766, and Ells of Vienna by .852. SQUARE YARDS May be readily produced from LINEAL YARDS, METRES, AUNES, and BERLIN ELLS, of any width from inch to 72 inches, by the use of the following table and rules, substantially copied from a manuscript kindly furnished for this work by Mr. H. MILLARD, Entry Clerk at the NEW YORK CUSTOM HOUSE, where it has been in use for some years. Metres are estimated at 39.37 inches, according to Act of Congress, July 28, 1866, Chap. 301 (ante, Part III, p. 31); Aunes (of Lyons and Switzerland only), at 1.25 yards, and Berlin Ells at .73 of a yard. Widths. .1-72, or 1% of 1-9 of the lin. yds. will give the sq. yds. 36 inches. Lineal yards Square yards. ...1-36, or 4 of 1-9 and of 1⁄2, and 1⁄4 of 1⁄4 of 362 Lineal yards..... 39 40 40/%2 41 4112 42 422 43 " " 43% 66 44 442 45 " " " 462 |
