Background & Context
The metric system was officially adopted by France in 1799 and is now used by the vast majority of countries worldwide. The United States, Liberia, and Myanmar are the only countries that have not officially adopted the metric system. One nautical mile equals exactly 1,852 meters and is used in aviation and maritime navigation.
