Excerpt from Treatise on General and Industrial Organic Chemistry, Vol. 1
In this translation it has been deemed undesirable in most cases to convert the metric weights and measures into those of the English system, but, in general, prices are given in British currency, twenty-five lire being taken as the equivalent of one pound sterling. Where quantities are given in tons, the latter are to be read as metric tons of 1000 kilograms or 2204.6 lb. avoirdupois.
The abbreviations employed for the different units of weights and measures are those in common use, and temperatures are expressed in degrees Centigrade in all cases.
