Liang, qian and regional definitions
Modern mainland liang = 50 g and qian = 5 g. These are not the Taiwan or Hong Kong definitions. Select tai-liang (37.5 g) or tai-qian (3.75 g) explicitly for Taiwan. Hong Kong sima tael is 1/16 of a 604.78982 g catty; sima mace is 1/160 of that catty. This is unit arithmetic, not medication or prescription guidance. Historical definitions require their own period and source.
Sources: Taipei government measurement reference (1 tai-qian = 3.75 g); Hong Kong Chinese Medicine Council, Appendix 2 (sima unit ratios). Exact regional factors are retained until display rounding.
