Formula and Step-by-Step

cups × 328g/cup = grams
  1. Start with 1.23 cups of corn syrup
  2. 1 cup of corn syrup = 328g
  3. 1.23 × 328 = 403.44g

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

Measuring Tip

Liquid densities vary: oils weigh less per cup than water, while syrups and honey weigh more. This is why ingredient-specific conversions matter even for liquids.

Understanding the Units

What is a Cup?

In US cooking, a cup measures volume, not weight. One standard US cup holds 236.588 ml of liquid. Because different ingredients have different densities, a cup of one ingredient can weigh very differently from a cup of another.

What is a Gram?

Weighing ingredients in grams eliminates the variability of volume measurements. A cup of flour can weigh anywhere from 120g to 160g depending on how it was scooped, but 120g of flour is always 120g of flour.

Frequently Asked Questions

About 403.44 g, based on corn syrup having a density of 328g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of cups by 328 (grams per cup for corn syrup). For 1.23 cups: 1.23 × 328 = 403.44 g.
Weighing corn syrup on a kitchen scale is strongly recommended. It is thick and sticky, so it clings to measuring vessels. If you must measure by volume, lightly oil the measuring cup first so it slides out cleanly.
Temperature has a minimal effect on most cooking liquids. The density of corn syrup changes slightly with temperature, but the difference is usually less than 1-2% between refrigerator and room temperature. This conversion assumes room temperature.
Reverse the conversion: 403.44 g ÷ 328 = 1.23 cups. Or use the Grams to Cups converter.
