This chart is simply a diagram showing the relationships between common units in the Greek language from roughly 400 bce to 100 ce. It is not meant to suggest that, at some particular time and place, all of these units were in use. They were not.

Some exceptional units not included in the chart:

sources

Thus the pyramids are 100 orguia high, and 100 orguia equal 1 stadion or 600 pous; the orguia measuring 6 pous or 4 pechus; the pous, 4 palaiste; and the pechus, 6 palaiste. [names of units given in singular]
