Why table salt needs its own conversion
Table Salt weighs about 288g per cup — notably dense — closer to syrups than most dry ingredients. REALISTIC UNIT: 1 tablespoon = 18 g (King Arthur). Kosher salt is lighter: Diamond Crystal 8 g/Tbsp, Morton 16 g/Tbsp. A cup is a unit of volume, so ingredients this different in density can't share one generic conversion factor — using a single "1 cup = X g" rule for everything will be wrong for at least some of what you cook.
Common measurement mistakes
- Using a generic cup-to-gram factor for every ingredient — table salt does not weigh the same per cup as most other ingredients.
- Measurement note: REALISTIC UNIT: 1 tablespoon = 18 g (King Arthur). Kosher salt is lighter: Diamond Crystal 8 g/Tbsp, Morton 16 g/Tbsp.
- Confusing weight ounces with fluid ounces when a recipe lists "oz" — they are not interchangeable.
