Common pitfalls and look-alike units
The market jin is 500 g and the liang is 50 g (1 jin = 10 liang) — a different system from the imperial pound (1 lb ≈ 453.592 g). In traditional Chinese medicine the old liang of 31.25 g (16 liang per jin) still applies, so prescription doses must not be converted with market units.
