Stu, I don't think anyone really knows what a pound or ounce is. Want to conduct a test? Go to the deli at any local supermarket and ask for something in an amount that is not either 0.25, 0.5, 0.75 or 1 lb. Ask for 10 ounces instead and watch the surprised look you get. They will ask you to translate that into pounds. Then tell them you have a recipe that requires only that amount and that is all you want to buy. You can even tell them that the amount is equal to 300 g. Then they will tell you they don't do metric. After which you tell them they obviously don't do American measures either or they wouldn't have such a difficulty filling the request. The next step is they get the manager. It is even more of a hoot when the manager can't figure it out either.
If you decide to try this test, make sure you keep a serious look the entire time and avoid smiling or laughing.
You don't even need to change degrees Celsius to Fahrenheit. All you need to do is remember that 30°C is hot, 20°C is warm, 10°C is cool and 0 °C is freezing. That is what you really want to know when a temperature is given anyway. Your body temperature is 37°C (98.6 is an exact conversion of the rounded 37°C). The human body can only withstand an exposure to a temperature of 50°C for a few hours before you die of heat stroke. If you need some more references then you can make your own and memorize as many as you need, but for the majority of innumerate people the range from 0 to 30 will suffice.

But popular opinion is that there's no impetus for abandoning the units we grew up with, other than helping visiting Canadians avoid confusion.
That is because most people don't really think about how much a fully functional metric America would improve their living standard by creating better jobs, make simple calculations easier and thus save money when shopping. It would decrease wastage due to measuring errors when using non-metric units. It would also save lives as there are many medical errors resulting in death from miscalculating dosage based on body mass in kilograms. There are a lot of good reasons. But most people are too ignorant to figure it out.

I'm sure Britain endured a similar debate when they decimalized their currency. But they still haven't fully adopted the metric system.
Not true about Britain but very true about the English. The non-English British have adopted metric more extensively then the English. Industry in the UK is fully metric as are the products in the supermarket. There are no dual labels. The deli scales are all in kilograms. But some people let their stupidity overcome them and insist on asking for pounds and ounces. This leaves the counter person free to oversell the products as it is up to the customer to compare what they have asked for versus what they see on the scale.
In reality it is not possible to get an exact pound even if a product is carefully weighed. UK scales only display to the nearest 5 g. Thus for a pound (453.6 g) the closest you can ever get is 455 g. But most shops will weigh out 460~480 g and just say "it's a little over". Only those who are opposed and have memorized the exact conversions may refuse to accept the amount and insist on being given a closer amount.

You can probably put it all down to stubbornness. Americans as a whole don't like being told what to do, especially by pointy-headed academics who think they know better just because they're educated.
I'm sure stubbornness is a human trait everywhere, but when something has long term benefits, ignorance and stubbornness are ignored and the change is made anyway. Then the hardships fall on those who resist. Let it be their punishment that they suffer as a result.

We've been metricizing since the 70's. It hasn't caught on. The overnight approach is probably best. Just announce that we're going metric as of midnight. But our fearless leaders ain't that fearless.
It has caught on where it is important and those that haven't grasped it are usually on the outside looking in. I just wonder how much of this economic depression we are in could have been avoided if the economy was 100 % metric.

Would all the roads around Detroit (Eight Mile, Twelve Mile, etc) have to be re-named as well?
No, why would they need to be? They're just names, not measurements.
