Of all countries in the world that has an officially established system of measurement, only Burma/Myanmar, Liberia and the United States do not use the International System of Units (SI). The United States use Imperial units and U.S customary units. That is not to say that SI is not in use in the U.S. The customary units are nowadays defined from SI units. And the National Institute of Standards and Technology uses it. To answer your question: the metrication of the United States is gradual and there is no fixed date where you can say that the US adopted SI. http://en.wikipedia.org/wiki/Metrication_in_the_United_States
