I have reverted the deletion of the Roman and Greek foot and digit entries. The grounds in the edit summary were "derived units". I am not sure what this means in the context of this list. I am aware of Berriman's theory that the Greek foot had a geodetic origin and the other units followed from this. However, this is at least controversial and the proper place to discuss this theory, if considered notable, is within the individual articles. Readers are bound to expect these units to be here, and if they are not, an explanation for their exclusion from the scope. I daresay that there is no incontrovertible proof that any of the units on this list have an anthropomorphic origin as opposed to merely having an anthropormorphic name. If it can be reliably sourced that such a division actually exists, in my opinion this should be indicated in the list in some way rather than outright removal.

Roman and Greek foot
I have reverted the deletion of the Roman and Greek foot and digit entries. The grounds in the edit summary were "derived units". I am not sure what this means in the context of this list. I am aware of Berriman's theory that the Greek foot had a geodetic origin and the other units followed from this. However, this is at least controversial and the proper place to discuss this theory, if considered notable, is within the individual articles. Readers are bound to expect these units to be here, and if they are not, an explanation for their exclusion from the scope. I daresay that there is no incontrovertible proof that any of the units on this list have an anthropomorphic origin as opposed to merely having an anthropormorphic name. If it can be reliably sourced that such a division actually exists, in my opinion this should be indicated in the list in some way rather than outright removal.
