How Much Is 18 Grams of Table Salt in Cups?
18 grams of table salt equals 0.06 cups. Table salt has a density of 288g per cup. Because grams measure weight and cups measure volume, the result depends on the ingredient's density.
Formula and Step-by-Step
- Start with 18 grams of table salt
- 1 cup of table salt = 288g
- 18g ÷ 288g/cup = 0.06 cups
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Table salt is the densest common salt at 288g per cup. It is significantly heavier per measuring cup than kosher salt because the fine crystals pack tightly.
