Formula and Step-by-Step

grams ÷ 288g/cup = cups
  1. Start with 18 grams of table salt
  2. 1 cup of table salt = 288g
  3. 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.

Understanding the Units

What is a Gram?

A gram (g) is a metric unit of mass equal to 1/1000 of a kilogram. It is the standard weight measurement for precise baking worldwide. Professional bakers prefer grams because they are more accurate than volume measurements.

What is a Cup?

A cup is a US customary unit of volume equal to 236.588 milliliters or 8 fluid ounces. It is the most common volume measurement in American recipes. One cup can be divided into 16 tablespoons or 48 teaspoons.

Frequently Asked Questions

About 0.06 cups, based on table salt having a density of 288g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Divide the grams by 288 (grams per cup) to get cups. For 18 grams: 18 ÷ 288 = 0.06 cups.
For the most accurate results, weigh table salt 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: 0.06 cups × 288g/cup = 18g. Or use the Cups to Grams converter.
