And back to red, white and blue for three phase colours. Well done Boris.

people advocating the “reintroduction of imperial measurements” in the UK is that they rarely actually measure anything and never have, so basically don’t have any real idea of what they are talking about
I could not agree more - I do not see folk queuing up to suggest we re-issue pre-decimal money. And I agree its a mess, 'low bridge 4,22m, 1/4m ahead. Right, clear as mud.
The reason imperial units got swept aside is that they are utterly useless for anything that requires conversion - it's lovely to buy beer or milk as a pint, but to work out how much it weighs, perhaps to design a milk float, any self respecting engineer will metricate it first.
It amazes me that America still bumbles along with 19th century units, and to be honest, I see no reason for us to copy their stupidity.

PS cable colours I am less fussed about there is nothing magic about 3rd phase being green , then after the war changing to blue, as earthing became green, and now grey for the last 2 decades - there are examples off all 3 still in service in the UK.

That's easy - a gallon weighs 10 lb.
We still use miles per gallon, though I find miles per litre easier 'cos we buy the fuel in litres. Multiplying by 4½ is not that difficult.
Furlongs (i.e. the length of a furrow) may have fallen out of use save in horse racing, and chains are even more outdated; but we still use acres, which are a furlong times a chain, or a reasonable day's work for a man with a horse and plough.
A pole as a measurement - 4½ yards has gone, but if you go punting, that is the length of the pole that you will be using.
Dividing something into 2 parts by weight is straightforward, so it makes sense to have 16 ounces in a pound. 10 is hopeless being divisible only once by 2 or 5.
It's amazing how many people claim to be unable to walk 20 metres, but perhaps not given that it is the threshold for getting a free car.
