Measuring Tip
Cornstarch is a fine powder that compacts easily. Spoon it into the measuring spoon and level off rather than dipping, which packs in more than intended.
Understanding the Units
What is a Pound?
The abbreviation "lb" comes from the Latin word "libra." One pound equals exactly 453.59237 grams. For rough mental math, 1 pound is slightly less than half a kilogram.
What is a Cup?
In US cooking, a cup measures volume, not weight. One standard US cup holds 236.588 ml of liquid. Because different ingredients have different densities, a cup of one ingredient can weigh very differently from a cup of another.

Close, but not exactly. The pounds to cups conversion for cornstarch may vary slightly between brands depending on moisture content and how the ingredient is measured.
The same weight of different ingredients fills different volumes because each ingredient has a different density. A pound of cornstarch fills a different number of cups than a pound of a lighter or heavier ingredient. That is why this converter needs to know which ingredient you are measuring.
