Convert from gallon [UK] to peck [UK]

Unit Definition (gallon [UK])
Currently the British use a larger gallon than either of the American gallons. The Imperial Weights and Measures Act of 1824 established a new unit for all volumes, liquid or dry, replacing all the other gallons in previous use in Britain. The imperial gallon, designed to contain exactly 10 pounds of distilled water under precisely defined conditions, holds exactly 4.546 09 liters or approximately 277.4194 cubic inches. The imperial gallon equals 1.20095 U.S. liquid gallons (British wine gallons) or 1.03206 U.S. dry gallons (British corn gallons).

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.
