I am watching a lecture on process costing (using Wiley) and the instructor said “Equivalent units are only equivalent on the basis of cost”

I can’t wrap my head around what this means.. I actually understand and can compute the Equivalent units easily but I don’t understand this sentence and I really want to :/
