My Toshiba branded TV's weather app is currently saying the wind speed is 7,168 m/s, which I make to be a little over 16,000 mph (7Km/s), and the barometric pressure is 103,000 mb which is about 100 atmospheres (103 Mb).
I did report it to the real manufacturer, who acknowledged the report, and there has been a software update since, but no change. It is probably, at three years old, too old to get many more updates.
Really? I'd actually expect at least five years, as many warranties last
that long these days.

Er, I think that should be 1013mb as normal atmospheric pressure? Your
maths works though even if the figure was wrong!
since 7.168 m/s would be plausible
Incidentally, the "m" in mb stands for "milli", so 103,000 mb would be
103 b rather than 103Mb, though you're right that it would be close to
100 atmospheres.

The display says 103 Mb, not 1013 Mb, or even the plausible 1013 mb. The programmer for that app clearly had no understanding of units and multipliers. I assume it is trying to display 103 cb, not that anyone
uses centi with bars.

No, normal engineering and scientific practice is to use powers of 1000. So
u (10^-6), m (10^-3), k (10^3), M (10^6) etc, but da (deca: 10), h (hecto: >100), c (centi: 10^-2), d (deci:10^-1) etc are deprecated - apart from >centimetres which are "allowed" because the centimetre is a convenient >measurement, and avoids "human sized objects" have to be large numbers of >millimetres.

That's probably locally measured, rather than from Germany; the TV
weather app will be using the internet.
mb and hPa are different ways of saying the same thing! It should only
show one. hPa breaks the rule about only using integral powers of 1,000
as multipliers, as h means a factor of 100.
(I presume mb were invented on the basis of mean atmospheric pressure
being close to a power of ten times the standard, Pascal, unit of
pressure, so scaling that by powers of 10 to make 1 atmosphere
approximately 1 bar.)

If you listen to the Shipping Forecast, in the reports for coastal weather stations you'll find that visibilities are given in miles (nautical) for distances over one mile, but in metres for distances less than that.

we used letters to denote 10 and 11, so there was always one digit in

from one size to another in the same type of measurement (ie all
lengths are related by factor of 12, all masses are related by factor
of 12 etc).

An old engineer colleague of mine described the introduction of the
metric system as 'metrifucktion'.
Mind you, he would also draw a set of cock and balls on any memo he
disagreed with, and then return it to the originator.
Those were the days....
That's another thing about the imperial system: it has multiple definitions for units of the same name:
- statute / nautical miles (and hence mph/knots)
- avoirdupois, apothecary's and troy ounce
- UK/US pint/gallon/ton
In each case, they are*almost* the same, but with an annoying fiddle-factor to convert from one to another.
What is the current convention for specifying altitude of aircraft? I'd always through that feet were used worldwide, but when I was on a flight
from Amsterdam to Paderborn (Germany), I heard the pilot referring to altitudes in metres.
It's interesting that radio standardised on quoting wavelengths in metres, and the (UK) National Grid on maps was in kilometres right from when it was first shown on OS maps in (I think) the 1930s.
I tend to think of the imperial system as "folk units" - widely used day-to-day for giving approximate lengths of things (a 6-foot length of 2x4" timber, a person's height being 5'10" or their weight being 13 stone) and
the metric system as the one used for any scientific/engineering practice. I estimate in imperial but I always measure and calculate in metric.

I had a rubber stamp which said "BULLSHIT"
I can understand the use of 12 for number of objects in a box: 3 and 4 produces a box that is more square than 2 and 5. But for all other
purposes, the fact that something has more factors is far outweighed by
the fact that it is not 10 and so is a real bugger to calculate. "God"
really ought to have given us an extra finger on each hand so we learned
to calculate in base 12 and had two extra symbols to denote what in base
10 we call 10 and 11. Hexadecimal would be a nightmare if the extra
digits had not been denoted by single characters A-F but were instead
written as two characters 10-15.

What went wrong with metricification was that the purists tried to
eliminate all non-metric unts by prosecuting people for using Imperial
units which produced a big backlash.
Then it got mixed up with the EU. The EU lovers thought any use of
Imperial was somehow anti-European - ignoring the fact that most
countries in Europe have non-metric units that are used in parallel with metric units. Of course this tended to make the many people who hate
the EU even more likely to avoid using metric units.

When more items were in dozens, people were more like to do calculations
in their head but not the simplest calculation involves the use of a calculator.
I used to have some friends' children stay with me and would often show
them simple 'tricks' to use with some calculation. I have seen kids use
a calculator to multiply by 5 or even 10!
Somehow I was never taught the tricks of mental arithmetic. So if I have
to add a column of numbers etc I always have to write it down to keep
track of the carry/borrow digits. A calculator makes it even easier, but failing that I*need* a pen and paper. I wish I could keep track of
carry digits as I'm adding numbers in my head, but I find that
inordinately difficult. I know my "times tables" up to 12, because I was taught them and have them in a mental lookup table, but anything beyond

trivial things like 15 and 20, 30, 40.

Though they are now just as likely to get out a calculator (mobile phone

Just as (apparently) a lot of children these days cannot tell the time
using an analogue clock/watch, because they are so used to times being displayed as 12:34. I find an analogue clock better for telling the approximate time at a very quick glance "it's about half past 12" but
digital much better for giving an exact time without the need for
counting minute-divisions. And if the analogue clock face only has
5-minute / hour marks then you have to interpolate which is a right
faff: "is the minute hand closer to the 4 or the 5 - is it 22 minutes or
23 minutes past the hour?" Easy enough - but slower than reading digits.

If it's twenty to the hour you can see at a glance how long to the hour, similarly with five to. With a digital clock you have to do a sum to
tell how long it is, and remember that there are 60 minutes to the hour,
not 100.

As far as I know, we in the UK can (still) use any units we want -
provided the equivalent metric is also clearly indicated.

Then of course you get the half-past or half-to confusion. English
denotes xx:30 as "half past xx" but German calls it "half to xx+1" -
"half past two" would be "halb drei" (half [before] three). When I had
to go over to Germany to demonstrate at a trade fair, I made sure I
said "halb nach zwei" (half past two) even though this was
idiomatically wrong, because at least it was unambiguous. Or else say
"zwei Uhr dreissig" (two thirty).
Same as numerical dates: once you learn that UK and US write numerical
dates differently, you take steps to avoid confusion: I tend to write
dates as 8 May 2023 because that is unambiguous, even if an American
might write it May 8 2023. On the other hand, 08/05/2023 could mean
August 5 rather than 8 May.

0 if you want to use this approach.
On the BBC News Weather forecast this morning, what was stated was
that there would be winds to 40 mph, but the subtitles interpreted
that as 240 mph.
That would be really noticeable, methinks.
It works for 9 as well.

I recently discovered that Argos also sell cheap radio controlled wall

What does Argos charge for one of these?

The one that annoys me is when I see 12am or 12pm. I've never quite sure which one of them is intended to be noon and which midnight. Logically,
noon should be represented as 12m.

Not in my experience with two wall-display digital clock/calendars, nor
with three temperature and clock/calendar display desk and
weather-station consoles. None of those have ever had an issue with the
time display.
I have had, and continue to have, infrequent problems with my Junghans
watch. About once a year it seems to receive an interfering signal from somewhere instead of that from DCF77. It then requires a manual reset, although I've never left it for 24 hours to see if it resets itself automatically at 0200/0300. Strangely, it has never failed to make the automatic adjustment correctly when the clocks go forward or back one hour.

Amazon also have a selection in various styles from £14. If you want
one with a red border, there's this-
Tesco misinterpreted the law and thought that loose items (eg sliced
ham, or cheese) could *only* be sold by the gramme, and that it was
illegal for them to respond to a request for "a quarter [pound] of
double gloucester".

They've solved the problem by closing the food counters, so you have
to buy in standard quantities.

Our local Tesco's reduced the size of the deli counter, and increased
the size of the pizza area. Oh dear. But they did open a salad bar,
but then closed the olive bar, making them only available in
pre-packed pots.

No, normal engineering and scientific practice is to use powers of 1000. So >>> u (10^-6), m (10^-3), k (10^3), M (10^6) etc, but da (deca: 10), h (hecto: >>> 100), c (centi: 10^-2), d (deci:10^-1) etc are deprecated - apart from

That's one of the reasons that car rev counters changed from displaying 10, >>> 20, 30 x 100 rpm to 1, 2, 3 x 1000 rpm. The other maybe even stronger reason

My weather station (made in China) gets its time from Germany ( I think)
pressure is "1033 mb hPa"
Is that because it's easier to state both (as 1mb = 1hPa) than try to
program it to show one or the other?!

The weather symbol is almost always wrong. I assume it gets that from elsewhere.
It's the time that it gets from Germany. The temperatures and pressure are consistent with info from an online Dutch lifeboat station about 10 km away. The
weather station included three external remote sensors. The sensors are compatible with an old weather station with a broken external sensor although the stations are a different make.

That's probably locally measured, rather than from Germany; the TV
weather app will be using the internet.
mb and hPa are different ways of saying the same thing! It should only
show one. hPa breaks the rule about only using integral powers of 1,000
as multipliers, as h means a factor of 100.
(I presume mb were invented on the basis of mean atmospheric pressure
being close to a power of ten times the standard, Pascal, unit of
pressure, so scaling that by powers of 10 to make 1 atmosphere
approximately 1 bar.)

If only God had either given us 12 fingers (so we would learn to
count in base 12 for everything) or else had devised a measurement
system which consistently used base 10 (since that's the base we
learn to count in).
10 can be divided by 1,2 and 5.
12 can be divided by 1,2,3,4 and 6.
This is the reason a lot of things came in 12s - easier to divide into
whole numbers. It wasn't done just because someone liked the number
12.
An old engineer colleague of mine described the introduction of the
metric system as 'metrifucktion'.
Mind you, he would also draw a set of cock and balls on any memo he
disagreed with, and then return it to the originator.
Those were the days....
I had a rubber stamp which said "BULLSHIT"
I wonder how long it will be before they close the in-store bakeries.
Tesco's tiger bread (baked in-store, when the machinery isn't broken or
being upgraded!) is considerably better than any pre-packed loaf.

Yes, I prefer tesco ISB loaves to other supermarket loaves, cuts better, toasts better and seems to last a day or so longer ... but the machinery
can be out of action quite often.

Interesting as well that two different stores a few miles apart produce
very different tiger loaves from presumably the same dough mixture and >cooking instructions. Maybe one oven is hotter than the other. Driffield >tiger bread is much softer and moister than Bridlington tiger bread
which can be dry right from day 1, and yet both are from Tesco. But it's
hit and miss whether the Driffield ISB is baking any bread that day, or >whether there is equipment fault, upgrading of equipment or they've run
out of the special paste which gives the tiger effect. About one trip in
four I return empty-handed :-( Actually "tiger" is a misnomer: the
bread is dappled like a giraffe, not striped like tiger.
Tiger bread is just ordinary bread with some kind of browning agent - probably
sugar solution - painted on top.
