I have the same experience. I'm an American expat so sometimes people will explicitly call out celsius for my benefit or as a joke, but yeah, nobody ever says celsius when they talk about the temperature here. "What's the temperature?" "It's gonna be 21." "Got it, thanks." That's how it usually goes.
