'Gewohnt' (usual/used to) is the past participle of the reflexive verb 'sich gewöhnen' (to get used to). This origin explains the meaning of familiarity and habit.

After three weeks, the noise had become the usual background noise for him.
To express that you are used to something, you use the fixed structure 'etwas (Akkusativ) gewohnt sein' (to be used to something). The object is always in the accusative and used without a preposition.
Ich bin die Kälte in diesem Büro gewohnt.
I am used to the cold in this office.
If you want to say that you are used to doing something, you use the structure 'es gewohnt sein, … zu + Infinitiv' (to be used to ...-ing). The word 'es' is a fixed placeholder here.
Er ist es gewohnt, lange zu arbeiten.
He is used to working long hours.
In the meaning of 'üblich' (usual) or 'vertraut' (familiar), 'gewohnt' (usual) stands before a noun like a normal adjective and is declined. It describes that this noun is the normal or expected one.
Wir trafen uns zur gewohnten Zeit am gewohnten Ort.
We met at the usual time in the usual place.
known
'bekannt' and 'gewohnt' can both have to do with familiarity. You use 'bekannt' when you already know something, or have seen, heard, or experienced it before. 'gewohnt' means that something has become normal for someone, often because it happens regularly. A place can be 'bekannt' to you because you have been there before. You are 'gewohnt' to a long commute when it no longer bothers you. 'bekannt' emphasizes knowing or recognizing something; 'gewohnt' emphasizes habit or being used to something.

Nach drei Wochen ist Lisa den frühen Arbeitsbeginn gewohnt.
After three weeks, Lisa is used to the early start at work.
Der Weg zum Bahnhof ist mir schon bekannt.
