gram-molecular weight

(abbreviation GMW)

noun

The quantity of a chemical compound equal to its molecular weight in grams; now usually replaced by the mole. Also called gram molecule. See mole⁴.Analogous terms, such as gram-molecular weight for the molecular weight of a compound expressed in grams, were similarly used....

Thus, the gram-equivalent weight of calcium is 40.08/2 = 20.04, half the gram-molecular weight.
For species that undergo changes in oxidation state in chemical reactions, the extent of change in the oxidation state determines the relationship between the number of gram-equivalents and the number of moles (gram-molecular weights).
