A US cup of corn syrup weighs roughly 328 grams, or 11.57 ounces. Weighing is always more repeatable than scooping, which is why professional recipes give grams.

Amount in US cups = 1
Or a weight to convert back = 100
Grams per cup used = 328 = 328
Weight = 1 * 328 = 328
Weight in ounces = 328 / 28.349523125 = 11.5699
Tablespoons = 1 * 16 = 16
Teaspoons = 1 * 48 = 48
Volume = 1 * 236.5882365 = 236.588
Cups in the weight you entered = 328 > 0 ? 100 / 328 : 0 = 0.304 878
Tablespoons in that weight = 0.304 878 * 16 = 4.878 05
Implied bulk density = 328 / 236.5882365 = 1.386 37

Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.

The formula

grams = cups x grams per cup
1 US cup = 16 tablespoons = 48 teaspoons = 236.588 236 5 mL exactly
1 ounce = 28.349 523 125 g exactly

Cup figures assume the spoon-and-level convention: fluff the ingredient, spoon it into the cup and sweep the top flat. Dipping the cup straight into the bag packs in up to 20% more.

The volume conversions on this page are exact by definition. Only the grams-per-cup figure is a measured convention, and it is stated above so you can substitute your own.
