Historical background
The seom (pronounced "suhm") has roots in Korea's Joseon Dynasty (1392-1897), when rice was currency. Farmers paid taxes in seom measures, a practice lasting until metrication in 1961. The Imperial gallon? Born from 1824 British Weights and Measures Act, it standardized wine and beer measurements across teh Empire. Funny enough, both units trace back to agricultural taxation systems!
