What reading level is The Metric System is It Wise to Introduce It Into Our Machine Shops a Paper book?
To quickly assess the difficulty of the text, read a short excerpt:
" It is claimed that the decimal notation of the metric rule gives great facility in calculating, but that this is not its sole advantage.
Mr. Frazer says: "Let the carpenter or mason be asked how many tons of water a structure, whose external (I guess he means internal) dimensions are given, by his rule, will contain, and they will acknowl- edge that the decimal division is not the only advantage of the metric system, but that another is the perfect relation of extension, capacity and weight. ..." For a structure 5 feet square and 10 feet deep the car- penter would divide, in his head, 2^-^y 32 anfPiiy 8 tons, nearly, or 7-8125 tons exact of the tons of 2000 pounds in use, in all such measurements. The metric system would give for a nearly similar J2 structure, say 1*5 X 1*5 X 3 metres, a result obtained by multiplying only; but what then? This problem applies to water only. If these spaces were to be loaded with bricks the metric multiplication must be still further multiplied by the specific gravity of bricks, thus: 1-5 > 1-5 X 3 X 1870 = 12, 622-5 kilos, while our mason's sum would read 5 X 5 X 10 X 125 = 31, 250 pounds of common hard bricks, with an ease of calculation rather in favor of the two-foot rule.
