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
In the United States, the decision to adopt the metric system was made by the federal government with the passage of the Metric Conversion Act in 1975. This act declared the metric system as the preferred system of weights and measures for United States trade and commerce.
The U.S. first opposed the metric system in the 19th century when Congress passed the Metric Act of 1866, which allowed but did not require the use of the metric system. Since then, the U.S. has been slow to fully adopt the metric system for everyday use, despite efforts to encourage its use in certain industries.
The US does not use the metric system.
Canada officially adopted the metric system in 1970 through the Metric Conversion Act. This marked the country's transition from imperial units to metric units for measurements.
There isn't a separate US metric system, the metric system is international and the same everywhere. So one kilometre in the U.S.A. is one kilometre.

It is to provide a simple and coherent system of measurement units which are agreed by all people. Unfortunately, the US, Burma and Liberia have failed to adopt it.
