I guess I'm not following or there is something I don't understand about those definitions. Is "length" a unit or is "feet" a unit (or both)? Here's what I'm seeing:Mister T said:All dimensions are units, but not all units are dimensions. The radian is an example of a dimensionless unit.
"Dimensions are physical quantities that can be measured, whereas units are arbitrary names that correlate to particular dimensions to make it relative (e.g., a dimension is length, whereas a meter is a relative unit that describes length)"

That appears to me to say that "length" is a dimension and "feet" is a unit and they are not interchangeable terms/concepts. Same goes for "dimensionless" -- what you are saying is the opposite of what I'm seeing:

[what comes after appears to hinge on this issue so I'll put it on hold.]
[edit] I've been replying as I'm reading and it appears the discussion covered this already. I think we're past it.
