How many cups of water are in 33 ounces?

If I assume you are talking about fluid ounces, then I can answer easily. Since there are 8 fluid oz. in one cup, then divide 130 by 8 and you get: 16.25 cups. This is also equal to one gallon plus two ounces or 1.0625 gallons.

However, if you are talking about 130 oz. by weight, then you have to know that one gallon of water weighs 8.34 lbs. and the calculation is as follows:

130 oz. is equal to 8.125 lb., which is .9742206 of one gallon.

Since there are 16 cups per gallon: 16 x .9742206 = 15.59 cups
