The definition originally used on this site was for the Hong Kong standard where 1 Chinese inch = 0.03715 meters.
More information is available at https://en.wikipedia.org/wiki/Cun_(unit)
The cun was part of a larger system, and represented one-tenth of a chi (Chinese foot). In time the lengths were standardized, and in Hong Kong, using the traditional standard, it measures ~3.715 cm (~1.463 in). In the twentieth century in the Republic of China, the lengths were standardized to fit with the metric system, and in current usage in China and Taiwan it measures 31⁄3 cm (~1.312 in).
Based on this description, the new definition will assume the modern Chinese standard, so 1 Chinese inch = 1/30 meters.
