Anyway...can you tell me what the difference is? I thought there is only one way to describe the alcohol content of a beer. What are this volume/weight things?
It's just what it says- another way to express alcohol content. Most labels in the US show "alcohol by volume", but "alcohol by weight" is used as well.
The ABV shows the amount of alcohol by the total volume, while the alcohol by weight is the percentage of weight.
To convert ABW to ABV, simply multiply the ABW by 1.25.
