How Much Is 1 Cup of Corn Syrup in Grams?

1 cup of corn syrup weighs 328.00 g. This is based on corn syrup having a density of 328g per cup. Because cups measure volume and grams measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 1 cup.

Formula and Step-by-Step

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

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

Mental Math Shortcut

For 1 cup of corn syrup, just remember: 328g. Double it for 2 cups (656g), halve it for a half cup (164g).

Measuring Tip

Sticky liquids like corn syrup are easier to measure if you lightly oil the measuring cup first. The liquid will slide out cleanly.

Understanding the Units

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.

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.

Frequently Asked Questions

About 328.00 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 cup: 1 × 328 = 328.00 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: 328.00 g ÷ 328 = 1 cup. Or use the Grams to Cups converter.
