There are a few ".5 km" signs in Carrickmacross pointing towards Inniskeen.

9.5 km at the N2 junction
10.5 km near the town centre

I passed this today, but missed the 'f' on the sign, and thought of this thread. It is advertising a local radio station, obviously.

There used to be an advance warning sign for a side road on the A13 in London (it just pre-dated Google) whose plate warned it was in 188 metres, obviously a conversion from 200 yards by someone both unnecessarily precise and who didn't know metric is not used. It was there for years.

During the New Year of 1981/82 I joined a tour that crossed the Sahara by Landrover. WHen travelling on one of the main north-south roads in Algeria, I saw many roadsigns pointing to villages a little off the main road that were rounded to the nearest 100 metres. (The distances were usually less than one kilometre).

Or perhaps someone measured it very badly and thinks the roundabout is 92 femtometres away. :coat:

It's not a great advert as it doesn't tell me the name of the radio station. :facepalm:

... For anyone under 50, anywhere in the UK, do they actually use imperial measures anymore, unless they absolutely have to? Metric just seems to make so much more sense, otherwise why don't we go back to using pounds, shillings and pence again? :confused:
As I often hear in the pub: "Yes please, 568 millilitres of beer, thanks" ...

Quite agree with your underlying point though!
In these days of 'shrinkflation' I can imagine there'd be a lot of industry support for redefining a 'metric pint' as 500ml. Would solve a lot of problems!

Back in the days of imperial measurement, does anybody know why the UK measured engine sizes in cc rather than cu in?

:idea: Because they're smaller so manufacturers could quote a bigger number?

Like temperatures on the weather forecast in shouty newspaper headlines ? High temperatures in F because the numbers are bigger, low temperatures in C because they are smaller.

These days you're more likely to hear engine sizes quoted in litres, so the imperial equivalent would be pints, eg 'What do you think of my new 3½ pint Audi?'

Ha ha, that sounds so wrong. The use of metric measures here is, I think, in no small part down to the influence of German engineers and manufacturers in the early days of the motor industry; their engines dominated the market, so their units became standard. Conversely, flying heights of aircraft are quoted in feet because of the involvement of the USA at the outset, and TV sizes are in inches because of the UK's role in its development.

I had wondered that my self at times and when did they start -- The RR Merlin was 27 litres, when made by Packard in the US it was a V-1650 (1650 cu in). Other RR Aero engine were also quoted in litres.

Pre-war Austin 7's had a 748cc engine and races were organised by the 750 Motor Club. Early engine were quoted as power output (hp) not displacement, but when displacement was quoted it always seemed to be in cc.

probably more to do with American dominance of consumer electronics. That said it did look funny in a German supermarket seeing TV's advertised in zoll (inches) with the official EU metric measurement in brackets.

TV sizes are instead inflated by quoting the diagonal. I'm not aware of anything else that's measured like that. Eg B&Q may sell me a 3m x 4m lump of wood, they won't insist it's 5m. :lol:
