Nah bro its 178, 165, 152, 147 etc etc.
Dont overthink it my man, I dont really worry about the weight its just the amateurs. its not like you got guys cutting down to 165/152 or whatever you are and then blowing up to 180s for the fight or anything. its the ammys man, your reach and everything blah blah, just be comfortable and relaxed and youll be fine a couple inches here or there doesnt mean that much your main thing is just to get that ring experience.
also its worth noting that (at least here in america) if you can get below 152 you only use 10oz gloves, but 165 and up use 12oz. UNLESS your planning on boxing collegiately in which every weight class uses 12oz, even the small ones
