Convert from barleycorn to braza [Texas]

Unit Definition (barleycorn)
The Barleycorn is an old English unit of length. The custom of using seeds as units of length or weight is very common in farming societies. In Anglo-Saxon England, where barley was a basic crop, barleycorns played this traditional role. The weight of a barleycorn, later renamed the grain, is the original basis of all English weight systems including the older troy system and the later avoirdupois system. As a length unit, 3 barleycorns were equal to the Saxon ynce (inch). The English foot was actually defined as 12 of these ynces, that is, as 36 barleycorns.

Unit Definition (braza [Texas])
The Braza is a traditional unit of distance in Spain and Latin America. In Spain it equals 2 varas, 8 palmos, or about 1.67 meters (5.48 feet or 65.75 inches). In Latin America the Braza tends to be larger. The Argentine Braza is 1.73 meters (5.68 feet or 68.16 inches), and under the Texas definition of the Vara the Braza would be 1.693 meters (5.556 feet or 66.67 inches). The Portuguese Braça is similar, but it equals 10 palmos or about 2.20 meters (7.22 feet or 86.6 inches).
