Shizhi converts between Chinese units as well as Hong Kong (Cantonese) units. Convert between length, area, volume and mass, to a metric unit.


We don't want to leave anyone out — so we've made Shizhi accessible. VoiceOver will read out your unit and it's conversion aloud, and we're continually improving the accessible interface to make it even easier for users with eyesight impairments.
