Study of Yeongjocheok and Industry-Academic Calculation Methods Using Scale and Circumference of Jaseungcha Dohae

Abstract

Different units of metrology were used in the Joseon Dynasty, such as Yeongjocheok, Pobaekcheok, Jolegicheok, and Jucheok. In many cases, Yeongjocheok and Pobaekcheok were of different dimensions depending on the region. Therefore, this study analyzed Jaseungcha Dohae of Ha BaeckWon to restore the scale of Hwasun Dongbok area in which Seokdang Na GyeongJeokyung and Gyunam Ha BaeckWon lived and made practical devices. The results of the analysis show that a universal Yeongjocheok of 30.6 cm was used.
