It is easier to list the countries that don't officialy use the metric system. Of the almost 200 countries in the world:

  1. Only a few small countries (some Caribbean nations heavily influenced by America), have not formally adopted the use of SI.
  2. The USA is the only significant holdout.

Most countries in the world use the metric system as their primary measurement system. This includes almost all countries in Europe, Asia, Africa, and South America. The most notable exceptions are the United States, Liberia, and Myanmar, which primarily use the imperial system.

(this copy was used by my grandmother and her sister when they were in grade school)

Which countries are using miles?

Miles are a part of the Imperial System (or US customary system). The only countries to use this system is the United States, however, Liberia is also considered to use this form of measurement. You will find Liberia listed as a Metric Nation and as an Imperial Nation (in form of measurement systems); this is because Liberia does not have an official system of measurements. Liberia tends to use the Metric System in forms of international trade and business, but will tend to use the Imperial System in forms of internal usage. The United States is also a Metric/Imperial Nation, however, it is more Imperial than Metric and you will probably never list it as a Metric Nation alone. Myanmar (Burma) also does not use the Metric System, however, they do not use the Imperial System; they have their own system of measurement known as the Burmese System. However, there are still many Metric Nations that still use forms of the Imperial System. For example, the United Kingdom, Canada, Ireland, Australia, the Bahamas, India, and Malaysia still use some forms of the Imperial System, but are official Metric Nations. Many other countries fall under this category as well, mainly countries that were at one time a part of the British Empire (as the Imperial System was made by the British Empire).
