Convert from cup [US] to peck [UK]

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.

Unit Definition (peck [UK])
The peck [UK] is a traditional unit of volume, formerly used for both liquids and solids but now used mostly for dry commodities such as grains, berries, and fruits. A peck is 2 gallons, 8 quarts, or 1/4 bushel. In the British imperial system, a peck is a little larger, holding 554.84 cubic inches or approximately 9.0923 liters. In Scotland, the traditional peck held about 9.1 liters for wheat, peas, or beans and about 12.1 liters for barley or oats. The word "peck", originally spelled "pek", comes from the name of a similar old French unit; the origin of the French unit is not known.
