Convert from gill [UK] to board foot

Unit Definition (gill [UK])
The gill [UK] is a traditional unit of volume for liquids, especially wine and other alcoholic beverages. The gill is 1/4 pint. In the British Imperial system, the gill equals 5 fluid ounces, 8.670 cubic inches, or about 137.7 milliliters. The unit is pronounced "jill", with a soft "g" sound. Its name comes a Latin word gillo for a small wine vessel.

Unit Definition (board foot)
The board foot is a unit of volume used for measuring lumber. One board foot is the volume of a one-foot length of a "standard board" twelve inches wide by one inch thick. Thus a board foot equals 144 cubic inches, or 1/12 of a cubic foot, or approximately 2.360 liters. If lumber is stacked neatly, we can compute the number of board feet from the dimensions of the stack, no matter how wide or thick the boards are. For example, a stack of two-by-fours 4 ft high, 4 ft wide, and 8 ft long contains 4 x 4 x 8 = 128 cubic feet, equivalent to 128 x 12 = 1536 board feet. The symbol fbm is an abbreviation for "foot, board measure."
