I have searched on the Internet but I do not feel I have found concrete information. Thank you, Lisa

Here's one source I've found that gives this information: The World Factbook Appendix E: Weights and Measures http://www.odci.gov/cia/publications/factbook/docs/app-e.html At the bottom of the page, it says Note: At this time, only three countries - Burma, Liberia, and the US - have not adopted the International System of Units (SI, or metric system) as their official system of weights and measures. Although use of the metric system has been sanctioned by law in the US since 1866, it has been slow in displacing the American adaptation of the British Imperial System known as the US Customary System. The US is the only industrialized nation that does not mainly use the metric system in its commercial and standards activities, but there is increasing acceptance in science, medicine, government, and many sectors of industry. Note that it's not quite accurate to say, as in your question, that these are the only three countries "not using the metric system"; we do use it for many purposes, just not officially - and in many countries that do officially use metric, traditional units are still used for many purposes, though sometimes illegally. - Doctor Peterson, The Math Forum http://mathforum.org/dr.math/
