This significantly expanded and completely revised second edition by Fritz Verdenhalven provides a comprehensive overview of the old measurement and currency systems. It takes into account the German-speaking region with its colorful variety of small states that thrived at the beginning of the 19th century. Everywhere, not only traditional units of measurement and weight were maintained, but also currencies, whose size, weight, and value could vary from country to country. This easily reveals the difficulties that merchants and traders faced in cross-border trade. The efforts of some local rulers to standardize the measurement systems in their regions brought little relief for trade. Finally, on January 1, 1872, the metric system was introduced, providing a fundamental and uniform determination of measurements and weights. This book is thus an indispensable resource for anyone encountering references to masses, weights, and currencies in documents, purchase contracts, or correspondence from earlier times. Their meanings are carefully detailed in this work.
