"KPH" is not really a metric unit. It's a hybrid of metric (kilometer)
and something else (hour).
Converting some (non-metric) time units to metric:
1 minute = 60S (60 seconds)
1 hour = 3.6KS (3.6 kiloseconds)
1 day = 86.4KS
1 month (approx.) = 2.6MS (2.6 megaseconds)
1 year (approx.) = 31.56GS (31.56 gigaseconds)
Few (if any) people use metric for everything.
Note that I never said I recommended doing it this way.
Certainly it is. It my not be MKS, nor purely SI, but it is
metric. K==kilometers (1E3 meters) H==Hours(3.6E3 seconds), both
of which are SI units. KPH is then a "derived unit" and perfectly
If we are going to make these things simple, why not use a digital
clock and calender. Now if we can just get the rotation of the earth
to be an even base 10 number, compared to it's circuit of the sun..

When, after The French Revolution, the modern metric system was developed

Absolutely it's a stupid example -- although the demonstration of its
stupidity could have been better done, e.g. "If you're going 60 mph, a 300
mile trip also takes five hours. If you're only using one set of units, it
doesn't make any difference what they are."

Right on- by the way, I am 75 and have no problem with Celsius after our
long overdue conversion.
20-21C is fine , 0C cover your tender plants and watch for icy
atches. -40 C= -40F -Shirtsleeves are fine for 50-100 meters depending on
the wind as humidity is not a problem (better than NYC at temperatures near
100C makes sense as well as 0C in that boiling water is something you don't
want to wash your willie with.
It really is a matter of associating what you feel with the scale.
(Fahrenheit zero is based on the commonsense measure of the freezing point
of a saturated salt solution which everyone has on hand, and boiling point
is 180 degrees above the freezing point of "pure" water. Completely logical
of course )
As for thermostats- I wonder how many are accurate to within 1 division on
their scale and, if so, what does it mean at some other location in the
house or even the room?

Correction: the F scale was based the freezing point of that solution
and set at 32 degrees. Then 100 was selected as the normal human body
temp, or that is what I heard, not sure). Just why they set the
freezing point at 32 vice 0 escapes me.
Maybe to help those unable to handle negative numbers, but still
needed a way to express temperatures below freezing?
Of course, the REAL 0 point (no heat at all) is considerably lower
than either 0C or 0F.
I disagree, even though I have a science background (Physics). Metric
is great for doing that sort of thing, but for weather, not so much.
Fahrenheit is good because 100F is really nice and hot, and 0F is
really nice and cold. Bounds the temps that humans deal with rather
nicely. 100C is outside the range of experience (one hopes) and 0C is
coldish. Who cares what temperature water boils at?
The degrees F have nice granularity, so you don't have to deal with
fractional ones when describing the weather.
