In the great debate between metric and FFU I have never
been given an answer when asked as to exactly what defines a product as being a
metric product vs. an FFU product?
1.) If a product is designed and engineered as a metric
product with rounded metric dimensions, but marketed as an FFU product with
rounded imperial dimensions, is the product metric or FFU? Example, the
Floppy Disk
2.) Does rounded numbering define whether a product is
metric or FFU? What if a dimension is not rounded in either system of
units?
What about products that were once FFU but have been
changed to metric, like automobiles or IC chips? What about products
that contain hybrid dimensions?
3.) Does personal or official usage define whether
something is metric or not? If a person gave a description of an event in
metric units and the media converted it to FFU would the event still be
considered metric even if the FFU info dominates?
4.) Does accuracy of measurement determine the primary
system? If I measure a product in metric and someone else measures it in
FFU and the dimension in metric is closer to the true dimension is the product
then considered metric?
5.) Does following the rules of a standards body, such as
the ISO or IEC define a product to be metric?
What about a Country? What defines a nation or
people to be metric or FFU?
1.) The economy, such as the system in use in the
countries industries?
2.) What the country declares itself to be
officially?
3.) What the people actually use despite the official or
economic system?
Has anyone ever given this an thought and come up with
some valid answers?
