* Know your conversions: There are 4 fluid ounces in 1 cup.

* Calculate quarter cups: Since a quarter cup is 1/4 of a cup, it's equal to 1 fluid ounce.

* Divide total ounces by quarter cup size: 16 ounces / 1 ounce per quarter cup = 16 quarter cups

Therefore, there are 16 quarter cups in 16 ounces.
