As Lou stated, it's common for people to misuse the terminology or confuse the two. Maybe this will help you understand them even better.
Actually you use a form of a converter all the time. Just think about anything you own that is battery powered (DC) like say a cellphone or laptop computer. If your cellphone came with a wall charger, then this wall charger with the big box on the end, is a converter per se. It is converting the AC electricity from the outlet into DC power to charge your phones battery.
A charger/converter like pictured below would have 120 volt AC input and 5 volt DC output (since most cellphones use 5 volt DC). There is usually a label on the box that tells you how much input/output there is.
Now you may also own an inverter for your vehicle. This inverter is what you would plug into your cigarette lighter/12 volt outlet and then you would insert a cord that plugs into a 120 volt household outlet into it. This inverter takes 12 volt DC power from the vehicle and inverts it to 120 volt AC power......like the different types of inverters pictured below.
These inverters would have 12 volt DC input and 120 volt AC output.
A RV's converter and/or inverter (if equipped) do the same things basically, but just on a much larger scale.
