The number of amps going to an electrical outlet depends on the load that's plugged into it.
Common electrical outlets are rated for no more than 15 amps maximum although there are regular outlets that can be installed to handle 20. Outlets that handle more than 20 don't look "regular" so that no regular plug can be plugged into them by mistake.
Looking at your breaker box is a good idea to determine whether your outlet can handle 15, 20, or more, but you also have to know which breaker your particular outlet is connected to.
Breakers that are "ganged" (tied together) usually are on the same circuit and you have to add the two ratings together to come up with the amperage that circuit carries. Breakers like that are usually dedicated to a single large appliance like an electric stove or large air conditioner.
does it give you ohms or watts? if not give my husband time to look in his book. he's studying to be an electrician. if you want to know the formulas look on computer under ohms law if you want to do it yourself. :)

If it's a standard branch circuit duplex receptacle(one above the other w/white two hole cover) it is supposed to be on a 15 or 20 amp. breaker according to NEC (code). You can check it with and ammeter or by identifying the breaker that controls that receptacle.
How many amps are being used depends on what is being used at the time you check it with a amp probe at the panel also make sure if its a 20 amp breaker that 12 gauge wire is used if its a 15 amp breaker should be14 gauge wire to get a true reading of what's on that circuit turn on everything on that circut and then go to. Panel and load test that circut
