Is the water in the us different than the water in Europe?

Yes because the different places in the world that have water have different minerals in there water. For instance say water from Europe has more minerals in its water than the US does therefore; the water would taste different. Make sense?

no, the water is same but the thermometer scales are different

as we know c/5 = f-32/9 where c=Celsius and f=Fahrenheit. (this is the relation between them)

so, 100/5=212-32/9

which means 20=180/9
