Isn't the speedometer dual?

My dad's is pseudo-analog. Press a button and the needle
jumps to km/h range and the "mph" led switches to "kmh".
But then again, he's driving a big luxury boat. Anything
under 25K isn't likely to have this sort of neat technology.

All Toyotas I've ever seen have dual-labeling. Or are you driving a
continental car in Britain? If so, memorize this:
30mph=50km/h
35 = 60
45 = 70
50 = 80
60 = 100
70 = 110
It's not that hard once you get used to it.
When I was learning to drive, Canada was in the middle of converting their
road signs to Metric. My instructor taught me a quick way of converting the
signs if you had a car with an Imperial speedometer (which we did):
Drop the zero and multiply by six.
So, 70km/h becomes 7, then 7x6=42mph. You can round up to the nearest 5.
There seems to be nothing that simple going the other way, though.

Sure... A Km is slightly more than one half of a mile...so you
can cobble an estimate together...

Aren't there two sets of numbers on the speedo face? One set is large and
the other set is small. The small numbers in the USA are KPH, my guess is
that the small numbers in other markets would be MPH.

You could...
Let's see...One mile is 1.609km. That's one-and-a-half, plus about ten
percent.
I want to keep my mental gymnastics to a minimum, 'cause I'm weak with
math, so I'll work with halves and other easy stuff.
If we take 60mph as an example, I'd do this:
60 plus half of it again (one-and-a-half), so
60 + 30 = 90
Now I'd take the original, strip off the zero, making 6 (10% of 60).
90 + 6 = 96km/h
Then I'd round up to the nearest even number, so 100km/h.
100km/h is 62mph. Close enough.
Try 50mph:
50 + 25 + 5 = 80km/h.
Right on the dot.
-------------------------
Now if the number was odd, like 35mph, a common speed limit in town, I'd
round up to 40, then do the one-and-a-half thing, but not add the ten
percent.
40 + 20 = 60
60km/h is 37mph. Close enough.
Let's try 45mph.
Round up to 50
50 + 25 = 75
75km/h is almost 47mph. Close enough.
How about Michigan's 75mph?
80 + 40 = 120km/h.
It works!
Am I brilliant or what? ;^)

I guess it's a matter of perception and preference. Metric is easier if you
have to convert between units, but the need to do that is very rare unless
you're doing some sort of calculation, at which point you've usually got a
calculator or pencil handy anyway.
In daily life I don't think it makes a hill of beans of difference which
system gets used. Most daily measurements stay in one unit, with no
conversion. Gas in gallons or liters, distances in miles or km, etc. Even
if you're building a house, you'll leave your measurements in inches/feet-
and-inches or m/mm. For most measurement, all you're doing is a straight
substitution of one system for the other.
If you drive a car you make sure your speedometer (reasonably) matches a
number on a sign. Remember those little vinyl stick-on numbers you used to
put over your speedometer so you could correct for the new mismatch when
all the signs went metric? Straight substitution.
I was fine with Imperial and see no reason to change it.

The distances are relatively easy to convert.
What are hard to convert are the 'ratios' like mpg into the metric
equivalent (km per litre, I believe)
It's hard to get your mind around this, as one ratio is better as a
large number, and the other as a small number.
