On a pack of Hacendado ground coffee at Mercadona, in big letters: PACK AHORRO 2 x 500 GRS.
The symbol for the gram is g: lowercase, no period, no plural. It is not a commercial abbreviation, it is an SI symbol, and it never changes: 1 g, 500 g, 1000 g.
“GRS.” manages three mistakes in three letters: capitals (in the SI those are reserved for units named after people, like W or Pa), a plural “s” that symbols never take, and a trailing period that doesn’t belong either.
The correct form: 2 × 500 g
