Apparently because of evaporation in the casks when they were measured after the transatlantic crossing.Yes, but the only difference between the two is volume measurements, an imperial gallon is bigger than an american one.

There is no human alive that ever used “imperial”, the inch has been defined by being a fraction of a metre since the reign of Victoria. So this inch thingy is just like putting a different badge on a car, it doesn’t make it different, but you do it if you like
Ah - well - not strictly true, old chap. The inch was defined as being 25.4mm in 1930, not in Victoria's time. Also, the inch goes back way longer than millimetres, first appearing in an English document in the 7th century. It was derived from the Roman 1/12th of a foot, and in the 11th century was defined as the width of three barleycorns (that's 'cos they didn't have a vernier calliper in them days, so had to use something a bit handier as a standard).There is no human alive that ever used “imperial”, the inch has been defined by being a fraction of a metre since the reign of Victoria.

metric just seems a lot more logical, especially for fine measurements, fractions of inches just get confusing, and confusion leads to error. I do hate it when large measurements are given in mm, like 2400mm boards, not using metres here is a complete nonsense
... the UK was using metric extensively since the early 1800’s

I live in metric country, so I'm metric. However, Greeks do plumbing in inches, and a one inch pipe is 32mm diameter; half inch is 16mm . I haven't quite worked out why, but I'm working on it. I also know what an inch looks like, (second crease on my thumb), cubits are useful, but I pace in metres, not yards. Ask me how tall I am, and it's 6'3", but I weigh 95kg. Ask me what 6 inches looks like, and I can tell you, but 15cm? Not sure...It's all a bit of a mess
Either. So long as some clown doesn't decree it's 240cm.you could use metres, but it would be a 2.400m sheet, so the same number of characters

I think you’ve missed the point.Extensively? Not in my part of the UK 160 years after that. I didn't come across a single thing in metric until the mid '60s, and that was at school because they were obliged to teach it.
Metres are fine. Millimetres are fine. Centimetres are the work of the devil, invented to confuse us.
And here, millimetres were in common usage a division of an inch. So it's all rather academic. We've all been using barleycorns, ells and fathoms - we just didn't know it.I think you’ve missed the point.
By the 1960’s inches by definition were a number of millimetres. So you were using millimetres, you always have been,

A friend designed a car that he eventually put into production as a kit car. When he built the prototype he marked out all the metal for the chassis and was puzzled by an error of about 1mm when he compared the total length of material he had marked out compared to the total required by his design. He spent 3 days tracking down the probem before he would cut a single piece. It turned out to be the cumulative effect of numerous imperial to metric conversions.
A late friend, a pharmacist, pointed out that imperial measuremnts served a purpose - there were no decimal point errors in prescribed drug measurements so a many fewer accidental overdoses.
