You have a great point, that getting the world to switch would be very very hard. But it's not black and white, you can't compare that to anything. If there's a viable alternative to music notation that you know of and is superior to what we know as standard western notation, feel free to share. Your choice of example is interesting, considering metric has won, and the US is switching slowly. But there is no incorrec…
> the US is switching slowly. As a US citizen who is a metric fan and loves using it, in what way? The government did switch - in the 70s - according to its own statutes, it had to. It has crept up in various places (and I find it hilarious) innoculously, like in 2 liters of soda, or in how computer processors are talked about in mm² die areas. But the average American still uses imperial units religiously, anywhere…
1. Make sure everyone is educated in metric
2. Change the easy things: the paper size the government uses, the units on food labels, the measures legal to use for sales of loose food or other goods, the units the government uses for all types of reporting. (Therefore if businesses want government contracts, they'll need to use metric.)
3. Change other standards, like residential construction, preferred fasteners, wire sizes. Where old measures are required for compatibility, write "24.5mm" in the standard. If the dimension could be changed to 25mm without any side effect, use that.
4. Change other things people see daily: I don't know if doctors use metric in the US, but I assume they communicate to patients in old units. Change the default, but accomodate older people. Change the road signs. Is anything left?
The UK is part way through 4, but has been stuck there for decades.
