Frequently Asked Questions

About 2.51 cups, based on kosher salt (diamond crystal) having a density of 144g per cup. The exact amount depends on how the ingredient is measured and the specific product.
First convert ounces to grams (1 ounce = 28.3495g), then divide by 144 (grams per cup). For 12.75 ounces: 12.75 × 28.3495 = 361.46g, then 361.46 ÷ 144 = 2.51 cups.
For the most accurate results, weigh kosher salt (diamond crystal) on a kitchen scale. If measuring by volume, spoon the ingredient into the measuring cup and level it off with a straight edge rather than scooping directly.
Weight-per-cup values vary because of differences in how the ingredient is measured (spooned vs scooped), grind size, moisture content, and settling during storage. Our values use standardized measurement methods from established culinary references.
Reverse the conversion: 2.51 cups × 144g/cup = 361.46g, then 361.46g ÷ 28.3495 = 12.75 ounces. Or use the Cups to Ounces converter.
