That's really my point. Not Americanism or whatever.

I mean we have kilograms, meters and seconds. And they're the same for every country.

But "$" (dollars and other currency units) means different things, depending on the context. Similarly for ounces, pounds, feet, gallons, etc. So you're left with constructions like "US $" or "USD" or "USD $" vs "Can $" or "CAD" or "CAD $". Just as with "avoirdupois ounce" vs "troy ounce", "US gallon" vs "imperial gallon", and so on.

So anyway, I always write "foo USD", "foo EUR", "foo mBTC" and so on. To avoid ambiguity.
