Convert from ounce [UK, liquid] to cup [US]

Unit Definition (ounce [UK, liquid])
The ounce [UK, liquid] is a traditional unit of liquid volume, also called the fluid ounce to avoid confusion with the weight ounce. In the British Imperial system there are 20 fluid ounces in an imperial pint, so each fluid ounce represents about 1.733 871 cubic inches or 28.413 063 milliliters. A British fluid ounce weighs exactly one ounce at a specified temperature and pressure.

Unit Definition (cup [US])
The cup [US] is a traditional unit of volume used in recipes in the United States. One cup equals 1/2 (liquid) pint, or 8 fluid ounces. Technically, one cup equals exactly 14.4375 cubic inches or approximately 236.6 milliliters, not that anyone measures quite so precisely in the kitchen. American cooks use the same size cup for measuring both liquid and dry substances.
