English term or phrase: 1 3/4-inch drill bits
"Power drill with 3/16-inch and 1 3/4-inch drill bits"

J'ai trouvé 4,8 mm comme équivalent pour le premier (est-ce seulement correct ?) mais je peine pour le deuxième.

Merci

foret de 44 mm
Explanation:
...or probably more likely in that size 'mèche à bois', depending on what is being drilled!

1 3/4" = 1¾" = 1.75 inches = approx. 44 mm

4.8 mm is correct for ³/₁₆" — though a standard drill size of 5 mm is more likely to be required here. I doubt the final precision down to fractions of a millimetre is needed nor even helpful!

Please note that, even with the limited context given, it is not likely that an extremely high degree of precision could / would be required here; these are standard Imperial drill sizes, which are not necessarily all that precise in the first place! And it is only reasonable to assume that what interests the reader is "which standard metric drill should I use?"
Note that if this were some field where extreme precision is required, the writer would not have used measurements like ³/₁₆" or 1¾" — it would have been expressed in decimals of an inch, mils etc. — such as 0.1875" or 187.5 thou.
Fianlly, note that of course the situation would be totally different had it said, for example "ream the hole to a finished dimension of X ± 0.005 inch"

Peer comments on this answer (and responses from the answerer)
disagree  Pierrot de la L: in a professional context, Imperial units should be kept. I am NOT dogmatic about it. The thing is, we don't know the context, and as I said in the discussion, drill bit manufacturers have catalogs in metric units AND catalogs in Imperial units.
2 hrs
  -> It's absolutely impossible to be so dogmatic about it; in a REAL context, all that matters is what is most helpful to the reader! 'Professional' means 'doing the job properly' — though we do generally say it's wise to add the original units too.
agree  Cyril Tollari: Voilà une réponse très utile. Lucie dispose du contexte pour décider s'il faut laisser en unités impériales.
4 hrs
  -> Merci, Cyril !
agree  Antoine Dequidt: Réponse correcte. À ce diamètre il est peu probable que l'écart entre la valeur annoncée par Tony (ø44 mm) et la conversion réelle de pouces en millimètres (ø44,45 mm) soit capitale. Il reste effectivement à définir s'il s'agit d'un foret ou d'une mèche.

  -> Merci, Antoine !
neutral  Daryo: depending on the precision required this could be "good enough/perfectly usable" or dangerously wrong - context needs to be clarified.

  -> From the context given (hydroponics), it seems that incredible precision is unlikely to be required; in any case, the inherent accuracy of drill bits is not so very great, and it's obvious one would have no choice but to buy a standard one.
