English measurement system . It is also known by the name of imperial system . It is the union of all the non-metric units that are currently used in the United States and other countries whose main language is English, as is the case, of course, in England . It was taken as an official measure in only three countries in the world: USA , Liberia and the Union of Myanmar (formerly known as Burma ), although it is also used unofficially in other territories and countries with Anglo-Saxon influence, such as the Bahamas , Barbados , Jamaica ,Puerto Rico and Panama . However, between both countries there are a number of differences in the units, as well as there are numerous discrepancies between the systems that are currently used with those that were used in other times.

This is the International System of Units , different from the Imperial or English System and, therefore, the one used more frequently than other systems. Its name is often that of the metric system, since it is related to the decimal metric system of antiquity. Its origin, on the other hand, dates back to the early sixties of the 20th century, when the General Conference on Weights and Measures finished devising its basic principles.
