1 cup of table salt in grams — 292 g.

Why 292 g per cup

Table salt is the densest of the three common salts at 292 g/cup because the small uniform crystals pack tightly with no air gaps. 1 tsp ≈ 6 g.

Salt brand matters more than salt brand evangelists realise. Diamond Crystal kosher salt is barely half the weight of table salt per cup (142 g vs 292 g) because the flake structure traps air. Morton kosher sits in between at 240 g/cup. Most recipes don't specify which they mean — when scaling, always convert via weight.

The most accurate way to measure table salt

For recipes where the outcome matters — bakes, doughs, anything leavened — measure table salt on a kitchen scale set to grams. Set the bowl on the scale, press tare to zero, then add until the readout matches the gram value the recipe calls for. This removes the largest source of cup-to-cup variation: how you scoop.

The cup-based numbers on this page assume the “spoon and level” method — fluffing the ingredient in its container, spooning it into the cup, and levelling the top with a straight edge. Scooping directly with the cup packs more in, and can push the gram value up by 20-30 % for fluffy ingredients like flour and cocoa.
