Deletion of Introduction to the metric system

Comment: This is not a "simple case". The metric system is a subject that is known to have stymied generations of students in non-metric countries. This article is an honest attempt to present an accessible, non-technical introduction to the subject. In that sense it is not essentially different from Introduction to M-theory, Introduction to entropy, Introduction to evolution, Introduction to viruses, and many other "Introduction to ..." articles. Yes, in a sense they are |article forks, but not all forks are evil.  fork|POV forks should be deleted; they are an attempt to get around our WP:neutral point of view|neutral point of view policy, but that is not the case here. And forks that (usually unintentionally) simply duplicate existing articles should be merged and redirected. But this is obviously not a simple duplication. &nbsp
