Time for a Candian to enter the discussion:

Kilograms are a measure of mass as opposed to weight...

Ah, Yes Ted...
  ..and what is your weight in kilos, and height in meters...(w/o doing the conversion  )???

In all US industrial markets the metric system is in wide use.  If you buy a car, a bicycle, a motorcycle, or any other item of any complexity and you want to work on it yourself, your going to use metric tools, not English.

If your definition of the "entire world adopting the metric system"
means that every single measurement of anything in the world is out of the metric system, you are very much mistaken.  Measurements are done in a variety of different standards.  In threads alone there's about 20 different popular standards, and manufacturers and industries will adopt the most
unusual ones you can imagine.  For example, in auto air conditioning work, when the industry shifted from chlorinated
R12 the service fittings were all American Standard flare, available at any hardware store.  The logical thing would have been to shift to Metric ISO flare, wouldn't you think?  But guess what they did shift to?  ACME, that's what.  A thread standard that is used for worm drives on lathes and bench
vises, coupled with a compression flare.  It's unique in the AC industry and completely stupid because while the intent was to prevent DIYers from connecting their old R12 stuff to the new AC systems, you can buy ACME-to-standard flare adapters.

BSW Pipe thread, (ie: Whitworth) another non-metric standard, is used on virtually all water pipes in the UK, and in Australia.  MPH is also used on speed signs in the UK and Australia and until recently, in India.

In the US, virtually EVERYTHING made for foreign export is metric.

The lesson you should draw from this analogy is that in a post-IPv4-runout world, there are going to be "pockets" here and there of IPv4.  Most obviously, we will likely see IPv4 handoffs from ISP's to residential customers, for many, MANY years, long after the core is IPv6, using proxies and
translators at the ISP.  And why not, because any ISP doing that can use private numbers at no cost?  It's analogous to the local gas company is going to handoff your natural gas line to your home or business using NPT and English-measured pipe.  But, if the gas company is buying LNG from an
overseas supplier, it's likely going to be measured in metric.

But the idea that somehow conversion to the metric system hasn't happened in the US, or the UK, just because they have their street speed limit signs in miles, and their water pipe sizes and threads in century-old dinosaur standards that predate metric, is a fantasy.
