COMPARISON OF FRENCH AND English Weights and MEASURES. Containing the New or Metrical Weights and Measures of France, with their Proportion to those of England, both according to the Decimal System and the Systeme Usuel. 3,5317 cubic feet, or 26,419 wine gallons, 22 Imperial gallons, or 2,839 Winchester bushels. Kilolitre... Myrialitre... 35,3171 cubic feet, or 1 tun and 12 wine gallons. 353,17146 cubic feet. English WEIGHTS and MEASURES. The following Tables show the former state of English Weights and Measures; but an alteration was made from the 1 January, 1826, by the 5 Geo. IV. c. 74., an abstract of which will be found page 965; and which law confirms the existing standards both of weight and long measure. But it has made the following alteration in measures of capacity, that is to say, both in liquid and dry measures. Thus, instead of the three different gallons heretofore used, viz. the wine, ale, and corn gallons, one measure only is to be adopted, called the Imperial gallon, with its divisions and multiples, which are to be as heretofore for wine measure. But for corn or other dry goods not heaped, the divisions and multiples are to be as in corn measure. The Imperial gallon is to measure 277,274 cubic inches, and to weigh 10 lb. avoirdupois of water, at the temperature of 62 degrees of Fahrenheit's thermometer, the barometer being at 30 inches. The Imperial bushel is to measure and weigh eight times the above, and all the other multiples and divisions of the Imperial gallon are to be in proportion. All new measures in future are to be constructed on the Imperial plan; but the old measures may continue to be used,-provided their contents be marked on them, that is, the proportion which they may be found to bear to Imperial measure. The following Table shows the Contents of the different Gallons, both in Measure and Weight. The above Table will be found useful in comparing different vessels where gauging cannot be relied on. RULES FOR CONVERTING THE OLD MEASURES TO THE NEW, AND THE CONTRARY. 1. Wine Measure multiplied by 5 and divided by 6, will give Imperial measure, and the contrary. 2. Corn Measure multiplied by 31 and divided by 32, will give Imperial measure, and the contrary. 3. Ale Measure multiplied by 59 and divided by 60, will give Imperial measure, and the contrary. The Coal Measure is scarcely changed by the new law, and therefore will probably remain unaltered in practice. TABLES of ENGLISH WEIGHTS and MEASURES, compared with those of France. With sundry Explanations, &c. The grain troy is divided into 20 mites, the mite doit into 20 periots, and the periot into 24 blanks. 31,1027 ....373,2330 into 24 doits, the These divisions are imaginary; but there are real weights of decimal divisions to the thousandth part of a grain. This weight is essentially the same as troy weight, but differently divided. It is chiefly used for medical prescriptions; but drugs are mostly bought and sold by avoirdupois weight. DIAMOND WEight. Diamonds and other precious stones are weighed by carats, the carat being divided into 4 grains, and the grain into 16 parts. The diamond carat weighs 3 grains troy: thus, The dram is subdivided into three scruples, and each scruple into ten grains; the pound or 7680 grains avoirdupois equals 7000 grains. troy, and hence 1 grain troy equals 1,097 grains avoirdupois. Hence also...... 144 lb. avoirdupois. 175 lb. troy 175 oz. do. The stone is generally 14 lb. avoirdupois weight, but for butcher's meat or fish it is 8 lb. Hence the hundred equals 8 stone of 14 lb. or 14 stone of 8 lb. A stone of glass is 5 lb. A seam of glass 24 stone, or 120 lb. Hay and straw are sold by the load of 36 trusses. The truss of hay weighs 56 lb. and of straw 36 lb. The truss of new hay is 60 lb. until the 1st of September. -The custom of allowing more than 16 ounces to the pound of butter is very general in several parts of the country. |
