There are several units under 六徳.

These units were used with units of length, weight, volume, etc. For example, Japanese used 尺 (shaku, about 30.3cm) and 寸 (sun, about 3.03cm) for length before adopting the metric system. 1.234 尺 was called 1 尺 2 寸 3 分 4 厘, because there was no smaller unit than 寸.

The unit for ratio and interest rate was 割 (wari), which means 1/10. The interest rate of 15% was called 1 割 5 分. This 割 has become the basic unit of ratio, which makes smaller units confusing. Even though 厘 originally meant 1/100, it usually means 1/1000 now because 割 is used for 1/10.
