The international statute mile is exactly 1.60934 km; the nautical mile is a different unit (1 nmi = 1.852 km) that shows up in knots. Chinese market units follow the modern definitions 1 li = 500 m, 1 chi = 1/3 m, 1 cun = 1/30 m — older chi varied by dynasty (roughly 0.32–0.35 m), so do not apply them to historical measurements.
