Can anyone say how much does a gallon (or half) weigh? Preferably the contents only

I was wondering because of this thing on their site: "Our NPK values look low compared to, say, a generic 20-20-20. That's because liquids weigh much more than dry powders, and NPK is based on "percentage of weight"". Of course, 'liquids weigh more than dry powders' is BS when we think generally (like water vs flour, flour will sink), but I know that salts dissolved in water can make that liquid unusually heavy and much higher density than water.
So did anyone weigh theirs?
