I think one of the most impressive facts about the effectiveness of the colonialism of Celsius is that it's used even in places where it's incredibly incorrect at the one thing it's supposed to be better at.
Namely, the temperature at which water starts to boil.
It's the biggest argument people always have for why Celsius is better, but it only really applies at sea level/standard atmospheric pressure.
So, there are places that use Celsius because their colonizers did. This includes
Mexico: In Mexico City, water boils at about 92.56 C
Bolivia: In El Alto, the second-largest city, water boils at 85.9 C
Ecuador: In Quito, the second-largest city, water boils at 90.47 C
Colombia: In Bogotá, water boils at 91.26 C
Ethiopia: In Addis Ababa, water boils at 91.67 C
And so on.
(I used this Wikipedia page to find cities with over a million people and their average elevations, and I used this calculator to find the boiling points. Unsurprisingly, most of the high-altitude cities of size are in South/Central America.)
Anyway, the next time someone tries to argue that Celsius just 'makes more sense' because it's based on the boiling point, tell them 'not in Mexico City!' (It has the biggest population.)
