How many cups is 328 grams of corn syrup?

328 grams of corn syrup equals 1 US cup. This is the standard density figure used for both light and dark corn syrup.

How many cups is 100 grams of corn syrup?

100 grams of corn syrup is about 0.305 cups, roughly 1/4 to 1/3 of a cup.

Is light corn syrup the same weight as dark corn syrup?

Yes, in practice. Dark corn syrup has a small amount of molasses or caramel color added, which makes only a negligible difference to density, so the same 328 g/cup figure applies to both.

Why does corn syrup weigh more than a cup of water?

Corn syrup is a thick, concentrated sugar solution with a density of roughly 1.38 g/mL, well above water. That is why a cup of corn syrup weighs about 328 g compared to about 236 g for a cup of water.

What if my recipe uses tablespoons or teaspoons?

There are 16 tablespoons and 48 teaspoons in one US cup. One tablespoon of corn syrup is therefore about 20.5 g, and one teaspoon is about 6.8 g.

Does how I pour the corn syrup affect the gram weight?

No. Unlike dry ingredients, liquid corn syrup fills a measuring cup fully with no air pockets, so the 328 g/cup figure stays consistent regardless of pouring technique.
