The metric system was agreed upon by many countries in 1875 and the US was one of the founding members and officially metric since then. In more modern times it is called the SI system and used by all scientists and hopefully engineers as well. As for imperial system, if you are used to drink beer in the UK or Australia you certainly will feel cheated when you order a pint in the US, as measures are different in different parts of the empire. So yeah if you measure length in feet then it really depends on the shoe size.
