On this page, corn flour refers to the fine starch powder extracted from corn, known as cornstarch in North America and maize starch in some other regions. It is commonly used as a thickening agent in sauces, gravies, soups, and custards, and can also be used in some baking recipes to soften texture. One metric cup of corn flour weighs approximately 120 grams.

Corn flour (cornstarch) is a very fine starch that compacts easily when scooped, so measuring by weight gives more accurate and consistent results than volume alone. This page lets you convert corn flour between grams, cups, tablespoons, and more so your recipes turn out reliably every time.

Cornmeal is the whole corn kernel ground coarse, giving texture and flavour, while corn flour (cornstarch) is a fine starch with neither. The two are not a swap; corn flour thickens sauces, cornmeal builds cornbread and polenta. See our Cornmeal converter.

Arrowroot is a clear-setting root starch that swaps 1:1 for corn flour as a thickener. It sets glossier and handles acidic or frozen sauces better, while corn flour is cheaper and clouds slightly. They weigh close per cup (128 g arrowroot vs 120 g corn flour). See our Arrowroot converter.

Tapioca starch swaps 1:1 for corn flour and sets to a clear, glossy finish that freezes and thaws without weeping. Corn flour is cheaper and clouds a little. The two weigh the same per cup (120 g). See our Tapioca Starch converter.
