![3. Convert —9.6 R. into degrees of Fahr. and Cent. : —9 R. = + 11.75 F. —11.25 C. —0.6 = — 1.35 — 0.75 —9.6 R. = + 10.40 F. —12.00 C. If the proposed quantity extends to hundredths or thousandths of a degree, it may be converted by shifting the decrmal point of the proportional part either one or two places to the left. For example: 4. Convert + 52.246 C. into degrees of Fahr. and Reaum.: 4-52 C. = 125.6 F. 41.6 R. + 0.2 = 0.36 0.16 + 0.04 = 0.072 0.032 + 0.006 = 0.0108 0.0048 + 52.246 C. = 126.0428 F. 41.7968 R. Barometric Tables, Nos. IV. V. VI. ]. Required the value in French inches and Hnes, and Eng- lish inches, of a column of mercury 729.7 mill, in height. By Table IV. Inch. Lin. 729 mill. = 26 11.16 French. 28.701 English inch. + 0.7 = 0.315 0.0275 729.7 = 26 11.475 28.7285 Tables V. and VI. are used in the same manner, and serve for the conversion of French inches and lines and English inches into one another, and also into millimetres. By these tables a conversion may be made at a half or third of any of the num- bers, by doubling or trebling the given quantity, and then a half or third of the result will be the quantity required. Tables VII. to XIV. Are for converting the different French and English measures into one another, and arc used in the same manner as the pre- ceding.](https://iiif.wellcomecollection.org/image/b21982600_0006.jp2/full/800%2C/0/default.jpg)
