I disagree about all of your versions except the first one, since
- In the SI system, capitalisation is an integral part of what a certain letter means. M and m isn't the same thing, for example, and neither is s and S.
- W/s would mean watt per second, not watt-second, so that's a completely different quantity.
I do however know that there is a lot of misuse of these units, especially in the countries where the obsolete English system of units is still used for many purposes, engineering included. Many Americans write K for kilometer, instead of the correct km, and kph (kilo-pico-hour) instead of the correct km/h.
The whole idea with the SI-system (Système International d'Unités) is that it's used in exactly the same way everywhere, or confusion will still exist.
So while there may be many variants of English, there's only one of the international system of units. The writing of the names of the units is different in different languages, but not the symbols, and the symbols were used in the posts in this thread.
