This all depends on which branch of the military you are talking about.
In the Army, Air Force, & Marines the term "Captain" is typically interchangeable with the term "Commander." A Captain typically commands a company-sized element. Of course, there are also Battalion, Brigade, and Division Commanders as well who are much higher in rank than Captain.
Army/A.F./Marines Navy
Rank/Grade: Rank/Grade:
2LT/O1 = 2nd Lieutenant ENS/O1 = Ensign
1LT/O2 = 1st Lieutenant LTJG/O2 = Lieutenant Junior Grade
CPT/O3 = Captain LT/O3 = Lieutenant
MAJ/O4 = Major LCDR/O4 = Lieutenant Commander
LTC/O5 = Lieutenant Colonel CDR/O5 = Commander
COL/O6 = Colonel CAPT/O6 = Captain
In the Navy a Captain outranks a Commander as described above.

In organizations which have both ranks, Captain (US O6) is a higher rank than Commander (US O5). However, armies also use the title Captain, except it's a lower pay grade (US O3, equivalent to a naval Lieutenant). Military rank and organization in Star Wars is pretty convoluted, since in the movies the terms "Admiral" and "General" seem to refer to individuals within the same service (with Admiral being the higher of the two). This does not happen on Earth: Admiral and General are equivalent ranks (US O10) used in different branches of the service. Wow this is that same guy star wars ain't Real Life you know. Ranks are way further apart than ours Commander in star wars is higher than Captain
