When I were young we spoke of megacycles and milibarrs, now its megahertz
and hecto pascals.
It is a very good job none of these inventers who have been relatively
latterly honoured in this way had names like Bugga or worse!

Nearest I can think of is Dr Malcolm Taylor naming a unit of measurement
"The Malcolm" after himself and another one, "The Bernard" after
Quatermass. Or did you mean real people? Never mind, here's the clip...

Yes I meant real people. After all the guy Hertz existed as did barr and
Pascal.

I think the latter one was sneaked in by the French when nobody was looking,
as all airfield barometric pressures are now given in Hecto PASCAL's.

I'm waiting for the metric Foot.
There are digital miles and metric Tons already. Who was Ton? Maybe its
not a person. What could we have as a unit of weight? I guess it would have
to be mass as weight is not a very precise thing even on the earth it varies
with gravity.
There already is a Newton, so what about an Einstein or something else?

Bar is not named after a person: "The word bar has its origin in the Greek word
???? (baros), meaning weight." from the Wikipedia.

No such person as Barr, no such measure as barr. It's a bar, from the
Greek baros (weight). I've always used hertz [1]. My only real
non-metric holdout is that I can't quite get used to bar/Pa for tyre
pressures rather than PSI. I'm determined to do it though.

Incidentally, I noticed that in the indoor bowls, they'd give the jack
length in metres and then distances in feet an inches. For heaven's
sake, go properly zrgevp. We've been officially zrgevp for nearly
fifty years, after all.

I uster use cps (not the CPS) but adopted Hz a couple of decades ago.
Otherwise, much the same, including the difficulty with tyre pressures.

Just asked SWMBO about that because she was an indoor bowler until her club
folded, and watches it avidly on WWP. She doesn't know (actually she hadn't
noticed) - seems it's a peculiarity of long-mat which doesn't apply to
short-mat. But she pointed out that jack length has some formal status[1]
whereas inter-bowl distance is given only for the convenience of the
players.

[1]she did explain this formal status but that was 5 minutes ago and I've
forgotten now

It's a while since I visited a DIY shed: do they still sell 2"x4" timber
in 2.4m lengths?

All measurements are in zrgevp.

A very ungainly unit, yer Pascal. A 100# woman balances on her 1"x1"
heel, she's applying 100 lbs/sq.in. Tidy. A 100 kg woman (yes, large
woman) balances on her 1 cm x 1 cm heel (yes, spike heels) and that's
100 kg/sq. cm?

No, no, we gots to have the woman in Newtons so that's 980
newston/sq. cm. But yer Pascal is Newtons/sq. meter so that's 980
Newtons per 1/10,000th sq. meter or 9,800,000 Pascals. Calling it
9800 kilopascals doesn't make it any more intuitive.

Is there an officially approved sheddi version of "Feh"?

No I still have issues with metric. If somebody tells me so many feet I
instinctively see it in my minds Eye, centimetres does not work for me.

No idea about Bowls. There seems to be a Bowls subculture in this country
where weird rituals occur and nobody outside has any idea of what the heck
its all about.

So where is Hecto PASCAL's coming from?

Brian Gaff (02.02.2019, 11:01)
So is a barometer now a pascalometer?

There's a bowls club over the fence at the bottom of my garding, the
annoyances in decreasing order are

1) alarm going over several times a year (usually hot summer nights when
you want the windows open)

2) noisily slinging hundreds of glass bottles into a skip early(ish) in
the morning

3) patrons loudly saying goodbye to each other late at night

4) dinging of the refreshment bell

5) punch-up in the fishboat (ok, only once)

Promble is that you're mixing up force and mass.

> No, no, we gots to have the woman in Newtons so that's 980


Nope we have to have the force required to support her 100Kg mass
in a gravity field of 9.81m/s^2 applied through the 10^-4m^2 area of her
heel.

But yeah it makes for horrible numbers. Having the unit of force
equal to the force required to support a unit mass under Earth's gravity
makes for easy numbers - as long as you stay on Earth.
