You are missing the point. This isn't a debate over Imperial vs. Metric. This is a debate of which symbol abbreviations are acceptable.
It is a debate between for example using; FT, ft, or Ft.
Or between; km/h, kph, kmph, or kmh.
...and the big question being, if there is a standard to follow from the governing agencies or if it doesn't matter?
I'm sure it doesn't help that some have gone off topic and are jokingly talking about Metric vs Imperial.
I've changed the poll to allow you to change your mind.
