the small elderly minority who do want to use imperial can use it today because many goods have imperial measures shown alongside the official metric measures. At the moment, they don't have to, but in the future they will have no choice vast swathes of British consumers don't know the imperial system and vast swathes of that vast swathe don't *want* to know the imperial system. it requires creating a separate system of regulation of weights and measures, or else there's going to be a shit ton of fraudulent ripping off of customers This is about allowing shopkeepers to use *only* imperial measures, which is an absolutely ridiculous thing to do, because: Imperial measures are already allowed on a voluntary basis. No idea why anti EU haters invent bollocks like this. He has a loaf of bread - probably not knowing exactly what it weights, the baker aimed for 750g, but it usually is 780g or more - I want half of it, he cuts it with a knife, I get half a loaf of 341g - I pay for 341g. If I buy meat from a butcher, he cuts it and I pay what it weights: 888g? 997g? Does not matter. I buy packages of food all the time, and they have completely arbitrary weights: 80g, 125g, 85g, 240g, 250g - no one forces you to sell something with a round number. (Price per kg is a voluntary sign done by the markets, not required per law). And the price in the cupboard reflects it in the price per kg. Actually butter from Ireland in my supermarket here is something like 220g. You simply note the wage as "454g", wow so simple. No idea why it might/would be illegal in the UK - makes no sense. Many items were sold in 454g package sizes. There is a reason, why in the 18th century, scientists throw out any traditional measurement units completely and started from scratch. As this was pre-Wikipedia (in the 1980ies), I was lucky to have had a lexicon of measurements, coins and weight units, and until the next class, I had a whole sheet of paper of ounces, weighing between 22.1 grams (Dutch trade ounce) up to 26.400 grams (antique Greek copper ounce). The teacher then told me, that as a homework, I had to find out how much an ounce actually is. When I was in school, we had some boxing classes, and in the first one, the teacher told us the weight of the boxing glove (eight or ten ounces), and we got into a debate, how much grams an ounce actually is. Spain for instance had 45 different pounds (Spanish: libra), weighing between 350 g (Zaragoza) and 579 g (Pontevedra), each associated with its own ounce. It's just the Imperial pound that is the same everywhere.
The German pound (official name: preussisches Zollpfund, Prussian tariff pound) for instance is 500 grams, exactly half a kilogram. A pound is different in Germany (where it is still informally used, just not in print).
