grandarog. Yes, I have visited some in New Orleans & they are pretty tall. I assumed it was to keep them cooler in the Summer- from your post, obviously not. Of course we have the much more modern farce of the space shuttle made with Imperial & using some parts made in metric. Beyond comprehension!

In the deep South of USA (think "Gone with the Wind") the early new rich  plantation owners wanted opulent grand houses.
If you ever visit  you will find the Doors and Windows are huge and the ceilings very high,.
This was caused by the builders being given continental plans . All measurements were in centimetres which the American builders thought were inches ,hence the large scale buildings. A few were built before it was realised. :)

Hi,mostly light hearted problems created by decimilation ,but in at least one instance change of systems had a some what different effect .
I refer to the change in ionizing radiation regulations as used in the nuclear industry.the original dose rate was based on the REM -radiation dose equivalent  man,a whole new ball game compared to CIVERTS. SYSTEM ,

Interesting case of abusing the old measurements.  Aldi are selling packs of "quarter pounder" burgers.  Each burger is 73g.  A quarter pound in 113g!  More than a little naughty.

As this thread was getting very Model Railways orientated, I've started another under that heading for it seemed there were many who knew a lot about the subject & might make the thread very interesting.

Smiffy. Good lord! I remember talking with a chap with an Z gauge layout in a small suitcase; he said the problem was keeping dust off the rails for the slightest bit stopped the engine. p.s. I should have said N gauge as the next one down before Z, sorry.

I had TT, 3mm to the foot, or 1/100. Shame the 12mm track only represented 4 feet, you just had to remember not to look at trains head-on.

There's even a "T" gauge now which is less than half the size of "Z" gauge!

Nemo. Of course the continentals used HO, same track size but slightly different rolling stock. For my son- in my youth, I had O gauge- we bought  2nd hand TT, which I thought was by far the best, as small enough for a decent layout but not silly small like Z.

@Dave: Well caught (from last year), two mistakes in one post, must be going senile.  It's just as well that I didn't make that mistake doing my Yachtmaster/Coastal exam last autumn.  :-[
BTW, 1 nm is 1.85 km, so near enough 2 unless you are doing serious navigation in metric (and if so - why?).

I also grew up in "Imperial" days but, when you think about it, wasn't it strange, before and after the change, that OO gauge modelling (1:76) was always a mixture, being 4mm to 1 foot.

I've only just come across this thread & have read it with interest. I was born in 1930, so have only ever used Imperial; although towards the end of my working life, metric- or SI- was very much in vogue. I felt sorry for those who started metric at the change over for so much was - & still is, eg mph- in Imperial. Dave TT; yes, acre, they built houses then at 10 to the acre which put it into perspective. JohnF; I always used Btu's, & it was so easy to check out 3Btu's /ft3 to give a good indication of room heat loss. MartinR; afraid you are x60 out with the latitude. 1nm is 1minute of arc, not 1 degree. I nm is approx. 1.15 miles or 1 mile is approx. .9 of a mn.  In kms, " gawd knows"!
