I would like to know whether, if someone asks me "How are you?" and I reply "I'm nice, thank you", is the word 'nice' grammatically correct?

This question is too basic; it can be definitively and permanently answered by a single link to a standard internet reference source designed specifically to find that type of information.If this question can be reworded to fit the rules in the help center, please edit the question.
Yes, the word nice is grammatically correct here, but grammatical correctness doesn't mean idiomatic English, good English, or acceptable English. Say that to a native speaker and you will be dismissed as arrogant and narcissistic (You don't get to judge whether you're nice or not; that's for everyone else to tell you) or as a non-native speaker who doesn't know survival English.
The standard response is I'm fine, thank you. And you?
