By the 19th century, the pound sterling was widely accepted outside Britain. The American Nellie Bly carried Bank of England notes on her 1889–1890 trip around the world in 72 days. During the late 19th and early 20th centuries, many other countries adopted the gold standard. As a consequence, conversion rates between different currencies could be determined simply from the respective gold standards. The pound sterling was equal to 4.87 United States dollars, 4.87 Canadian dollars, 12.11 Dutch guilders, 25.22 French francs (or equivalent currencies in the Latin Monetary Union), 20.43 German marks, 9.46 Russian Rubles or 24.02 Austro-Hungarian krone. After the International Monetary Conference of 1867 in Paris, the possibility of the UK joining the Latin Monetary Union was discussed, and a Royal Commission on International Coinage examined the issues, resulting in a decision against joining monetary union.
