Length units such as chi, cun and zhang are tied to modern metric values in current mainland use. Older architecture, classical texts and regional references may need a separate source check.
Use this page as a quick lookup, then keep the original Chinese unit beside the converted number when accuracy matters. That is especially important for pricing, schoolwork, land records, shipping documents, recipes, medicine, historical writing or any source where the unit may be part of a larger standard.
