Usage of the term "English System" or "English Unit" is common in the US, but it is problematical. It can be ambiguous. It usually refers to either the Imperial System or the US Customary System, and in cases where these two systems differ, it is not clear which system is being described. Some people also call it the "British system" in the US. It is interesting to note that referring to this system as the British or English system almost only occurs in the United States, mainly causing confusion in the United Kingdom when reading from American sources.
