Formula and Step-by-Step

(ounces × 28.35g/oz) ÷ 288g/cup = cups
  1. Start with 128 ounces of table salt
  2. Convert ounces to grams: 128 × 28.35 = 3,628.74g
  3. 1 cup of table salt = 288g
  4. 3,628.74g ÷ 288g/cup = 12.60 cups

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Measuring Tip

If substituting table salt for kosher salt by volume, use roughly half the amount. For precision, convert by weight (grams) instead.

Understanding the Units

What is an Ounce?

An ounce (oz) is a US customary unit of weight equal to 28.3495 grams or 1/16 of a pound. In cooking, "ounces" refers to weight (avoirdupois ounces), not fluid ounces which measure volume.

What is a Cup?

The US cup (236.588 ml) is slightly smaller than the metric cup used in Australia and some other countries (250 ml). When following recipes from different countries, check which cup standard is being used.

Frequently Asked Questions

About 12.60 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.
First convert ounces to grams (1 ounce = 28.3495g), then divide by 288 (grams per cup). For 128 ounces: 128 × 28.3495 = 3,628.74g, then 3,628.74 ÷ 288 = 12.60 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: 12.60 cups × 288g/cup = 3,628.74g, then 3,628.74g ÷ 28.3495 = 128 ounces. Or use the Cups to Ounces converter.
