Ancient Chinese units of measurement varied over time and region, and their precise values could differ depending on the specific historical context. Here's what we know about some of the units you mentioned:

1. Ping (坪): The ping was an ancient Chinese unit of area, typically used to measure land or property. Its exact value varied over time and region but was generally equivalent to a square measure of land that could be cultivated by one person in a day.
2. Ching (丁): The ching was a unit of dry measure used in ancient China, particularly for grains and other dry goods. Its value could vary depending on the specific context and region.
3. You (斿): The you was a unit of length used in ancient China. Its exact value is not widely documented, and it may have varied depending on the period and region.
4. To (陀): The to was a unit of weight used in ancient China. Its exact value is not well-documented, and it may have varied depending on the specific context.
5. Cheng (乘): The cheng was a unit of length used in ancient China. Its precise value is not well-documented, and it may have varied over time and region.
6. Yo (余): The yo was a unit of length or area used in ancient China. Its exact value is not widely documented, and it may have varied depending on the specific context.
7. Kho (阔): The kho was a unit of length or area used in ancient China. Its precise value is not well-documented, and it may have varied depending on the specific period and region.
8. Chao (抄): The chao was a unit of length used in ancient China, particularly in the context of measuring cloth or textiles. Its exact value may have varied depending on regional practices and standards.
9. Co (古): The co was a unit of length or area used in ancient China. Its exact value is not widely documented, and it may have varied depending on the specific historical context.
10. Quei (碻): The quei was a unit of weight used in ancient China, particularly for measuring precious metals. Its precise value is not well-documented, and it may have varied depending on the specific context and region.

It's important to note that the information available about these ancient Chinese units of measurement can be limited, and their precise values and usage may not be well-documented. Additionally, variations in language, regional practices, and historical records can further complicate our understanding of these units. The base unit for capacity was Cheng where 1 [Cheng] is equal to 1.03544 \(\left[\mathrm{dm}^3\right]\) or 0.00103544 \(\left[\mathrm{m}^3\right]\). The largest unit was Ping where 1 [Ping] is equal to 500 [Cheng] or 0.51772 \(\left[\mathrm{m}^3\right]\). The smallest unit is Quei where 1 [Quei] is equal to 0.0001 [Cheng] or \(1.03544\cdot 10^{-7} \left[\mathrm{m}^3\right]\).
