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.
