Yes Brian, here in Aboyne we do all the time. One of the nicer features of
the Rover 75 is the button on the dashboard that allows you to see all
temperature displays in either Celsius or Fahrenheit. Naturally, we ageing
Imperialist and ex-Colonial set it to the latter.
Teaching oilfield stuff at Robert Gordon University, we teach our students
from all around the world how to work in US Customary units, since they are
extensively used in the oil and gas industry. It is quite common for
drilling operations to be conducted in a mixture of units: inches for the
diameter of the pipe used and metres for well depth, barrels for drilling
mud, kilos for the dry chemicals being added. Having done a lot of work for
a large number of operating companies around the world, I can tell you that
most use a mixture of units and there is very little consistency. This keeps
people on their toes! It forces them to think about the units they are
using.
I always felt that a system which had factors of 2, 3, 4 and 5, as £sd did,
had much to commend it to those needing to do mental arithmetic. With
computers, there is no advantage in one system over the other, but, I would
point out that the Imperial Pint is larger than 500 ml and therefore much to
be preferred when it comes to drinking beer. Of the course, this is where
the Americans, with their older, wine-gallon-based pint, do themselves a
disservice. Our pint is based on the weight of water: 1 Imp. Pt. = vol. of
20 oz. water at 50°F, if my memory serves me right.
As one who marks student papers, the frequency of order of magnitude errors
is greater with the metric system than with USC or Imperial, since the last
two make them think about the value of the answer. In other words, the main
problem with the metric system is that the answers tend to look the same, so
it's easy to be out by an order of magnitude or two and not notice.
Cheers,
Owen.

I'd be worried if the weather was 90 Centigrade as well! :-)

Degrees F or C?
If F, I can believe it, but C I think I'd be worried. I've always
worked on the basis one could put a hand on a diff, but you'd not want
to leave it there.

Anyone know what the normal temp for a running diff is? Just got back
from a 40 mile run in the Plus 4(TR3) in 90+ weather and checked the
diff with a infrared gun. Read 144. Is this normal?
