convert 384 fluid ounces to gallons?

I know a cup is 32 fluid oz

but if you do not
8 oz/cup * 2 cup/pt * 2 pt/qt * 4 qt/gal = 128 oz/gal

but I did

32 oz/qt * 4 qt/gal = 128 oz/gal

384 ox (1 gal/128 oz) = 3 gal

sorry, a qusrt is 32 oz

by the way:

a pint is a pound the word around.

This is an approximation
a pint of water is indeed about one pound weight
a half kilogram of water also is also about a pound weight and in Europe a half kilo is sometimes called a "pound". That is half a liter.

To convert fluid ounces to gallons, you need to know the conversion factor. In the United States customary system, there are 128 fluid ounces in a gallon.

To convert 384 fluid ounces to gallons, you can use the following formula:

Gallons = Fluid ounces / 128

Plugging in the values, we get:

Gallons = 384 / 128

Dividing 384 by 128, we find that:

Gallons = 3

So, 384 fluid ounces is equal to 3 gallons.
