Corn syrup, Cups to Grams & Grams to Cups
1 cup of corn syrup = 328 grams · 100g = 0.3 cups
Corn syrup is a thick, clear glucose syrup that weighs about 328 grams per cup and resists crystallising, which is why it keeps fudge, caramels and pecan pie smooth. Light corn syrup is nearly flavourless; dark corn syrup has caramel colour and a molasses-like note added. It is not the same as high-fructose corn syrup.

How to measure corn syrup accurately
For the most reliable baking results, weigh corn syrup on a kitchen scale rather than scooping by volume. One US cup of corn syrup weighs about 328 grams (11.6 oz), but the exact figure changes with how tightly it's packed and the brand. Scooping straight from the bag compacts corn syrup and can leave you 15 to 20% over, so spoon it into the cup and level it off for the closest match to the figures above. Use the tables for quick reference, or the converter for any custom amount in cups, grams, ounces or tablespoons.
Tip: Grease the cup before measuring corn syrup so the sticky syrup releases cleanly, and scrape the cup with a spatula to get every gram.
