Weights and Measures are the Nephites’ named system for reckoning gold and silver according to value and for measures of grain. The Nephites gave names to “the different pieces of their gold, and of their silver, according to their value,” and they “altered their reckoning and their measure, according to the minds and the circumstances of the people” until the reign of the judges, when king Mosiah had established them (Alma 11:4). The gold reckoning included “a senine of gold, a seon of gold, a shum of gold, and a limnah of gold” (Alma 11:5).
A senum of silver was equal to a senine of gold, “and either for a measure of barley, and also for a measure of every kind of grain” (Alma 11:7). The amount of a seon of gold was “twice the value of a senine,” and a shum of gold was “twice the value of a seon” (Alma 11:8–9). A shiblon was half of a senum and was “for half a measure of barley,” while an onti “was as great as them all” (Alma 11:13, 15).
