04 /Modern Chinese unit context
Use the stated modern mainland value for ordinary current contexts. Check historical, regional or specialist sources before treating the result as final.
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.
