I was in the bank the other day and the teller asked me how much I want to "convert" my money into USD.

Is this the right form of usage? Cambridge dictionary [defines](https://dictionary.cambridge.org/dictionary/english/convert) convert in many ways but all of them somewhat relate to a change of essence of whatever is being converted. 

However, I think my money is not changing its essence, I'm just exchanging with money in another currency which is arguably similar buying milk from the grocery store. (Exchanging money vs money or money vs good)
