Canada is one of those "rest of the world places".
Officially uses metric but the general population here (unless they are recent immigrants or work in the medical field) will tell you their height in feet and inches, their weight in lbs, they will tell you a recipe using Fahrenheit. Pizza is measured in inches. If you buy food, like deli meat, it is displayed in grams on the scale but a lot of people will ask for a half lb or whatever still. We use km for speed but we still use square footage if you are selling a house.
Unless they are boomers or older, we will use Celsius for the weather though.
I remember growing up learning metric and it was fine, everything made sense, then when I hit college was forced to learn American imperial for my job field cuz that's what the American standard was. I hate that I think in inches and feet for a lot of crap now. It's irritating switching back and forth depending on what you are doing.
There's ton of weird niche stuff. Mostly cycling related here but you get the point...
Bicycle pedal axle thread size
Bicycle wheel and tire sizing (actually metric standard but inches in common language)
Also wheel size on cars
Bicycle steerer tube diameter
10mm qr axle diameter on hubs (3/8" actually)
25.4mm handlebar clamp diameter sounds oddly familiar...
Most proper denim pants are sized in inches, even from non-US countries.
But of course vanity sizing is a thing so a size 36 is closer to 38in unless explicitly specified, and most online retailers provide true sizing in cm anyway, so there's that.
I guess also bike wheel sizes, screens sizes. Height and body waist? Are you talking about the UK? Europe only uses inches for products that have certain expected sizes.
And yet you call Americans dumb for not adopting the metric system. Why would we think we would do a better job than you? I would much rather use the system my grandpa grew up with rather than use the hybrid abomination that the UK uses.
I'm a Scottish nationalist and republican (in the British sense). It's one of my pipe dreams to see an independent Scotland adopt the metric system fully but I kinda doubt it will ever happen.
Wild, I didn't know there was a different gallon measurement (There's a few apparently).
mostly unrelated, but after poking around on Wikipedia, I've also learned that there's two different versions of fluid ounces (Edit: that are used actively in the US, forgot to add that), and both are used on food labels simultaneously, but relating to different things.
For serving sizes on nutrition labels in the US, regulation 21 CFR §101.9(b) requires the use of "common household measures", and 21 CFR §101.9(b)(5)(viii) defines a "common household" fluid ounce as exactly 30 milliliters. This applies to the serving size but not the package size, package sizes use the US customary fluid ounce.
I suspect that might relate to the smaller english/canadian fluid ounce and imports. they're very close, you only start to easily see a difference around 5 ounces. I run a bar in Canada, and i catch inspectors and suppliers constantly playing fast and loose with Imperial and American standards ounces and pints. Canadian law saws if you are serving a pint of beer, it has to be a proper Imperial pint of 20 ounces, from the big English gallon, if you call it a pint. you can serve any size you want if you don't call it a pint. i constantly see competitors passing off 16 American ounces as a pint. The revenue guys check that your dispensing machines are putting out an ounce but won't tell you whether they are using a Imperial or Standard ounce, i'm pretty sure they're using American ounce devices when they shouldn't be. Supposedly we're a metric country but liquor and cattle definitely aint.
I'm the one that doesn't want to learn anything then you drop an "England" on me? I'm Scottish or does that not matter because is it too much for you to learn that the UK is more than England?
The difference of Scotland, Wales, and England matters to you and maybe the French. To people on another continent talking about measurement systems...well,,,I'm aware Scotland has their own passport. If you want me to know you're at at a Scottish gas station, say that. I'm sorry, but Scotland didn't run a giant empire for 200 years, England did. It's kinda funny you live in one of the very few countries the English never conquered and no one cares.
My brain is filled with far too much shite about measurements. I love all of it. I'm a great lover of odd and obscure imperial units. Please don't try to tell me I don't want to know.
