How Much Is 3 Cups of Kosher Salt (Morton) in Ounces?
3 cups of kosher salt (morton) weighs 25.50 oz. This is based on kosher salt (morton) having a density of 241g per cup. Because cups measure volume and ounces measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 3 cups.
Formula and Step-by-Step
- Start with 3 cups of kosher salt (morton)
- 1 cup of kosher salt (morton) = 241g
- 3 × 241 = 723g
- Convert grams to ounces: 723 ÷ 28.3495 = 25.50 oz
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Always check which salt brand your recipe specifies. Substituting one for another by volume can double or halve the salt content.

Understanding the Units
What is a Cup?
There are three cup standards used worldwide. The US cup (236.588 ml) is used in American recipes. The metric cup (250 ml) is standard in Australia, New Zealand, and some parts of Asia. The imperial cup (284.131 ml) appears in older British and Canadian recipes. A metric cup holds about 5.7% more than a US cup, while an imperial cup holds about 20% more. Using the wrong standard can noticeably affect a recipe.
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.
