Corn Syrup — Grams & Cups Converter
1 cup of corn syrup weighs about 328 g. So 100 g ≈ 1/3 cup, 200 g ≈ 5/8 cup, and 300 g ≈ 7/8 cup. Convert any amount between grams, cups, ounces, tablespoons and millilitres with the calculator below.
💡 Tip: Oil the measuring cup first so corn syrup pours out cleanly. Light corn syrup is mild; dark has a deeper, molasses-like flavour.

Measuring corn syrup cleanly and light vs dark
Corn syrup is dense and very sticky — a cup weighs about 328 g (11.6 oz), with each tablespoon near 20.5 g. Lightly oil or spray the measuring cup first and it slides out without clinging to the sides. Light corn syrup is mild and nearly clear; dark corn syrup has caramel and refiners' molasses added for a deeper colour and flavour. It's prized in candy, pecan pie and frostings because it's an invert syrup that resists crystallising, keeping fudge and caramel smooth. A common US bottle is 16 fl oz, roughly 2 cups.
