early 15c., from Latin aequatus “level, levelled, even,” past participle of aequare “make even or uniform, make equal,” from aequus “level, even, equal” (see equal (adj.)). Earliest use in English was of astrological calculation, then “to make equal;” meaning “to regard as equal” is early 19c. Related: Equated; equating.
