How to measure corn kernels

Fresh and frozen corn kernels weigh the same per cup. Drain canned corn first.

Because a cup measures volume rather than weight, the most reliable way to measure corn kernels is with a digital kitchen scale. If you are working from cups, keep your technique consistent every time so your results are repeatable. For more, see our guide on baking by weight versus volume.

Substitutes for corn kernels

Equal frozen corn (1:1, thaw and drain for most uses) (Cook Plate Fork)
Best texture match for fresh kernels. For roasting or baking, can be added frozen directly. Add a pinch of salt to match canned's seasoning.
1½ cups drained canned corn per 15 oz can (soups, casseroles, sautés) (Flavor 365)
Drain well — canned corn sits in salty/sugary brine. Reduce added salt accordingly. Avoid as a fresh swap in salads or salsas where pop and bite matter.

Corn kernels conversions: FAQ

Why doesn't a cup of corn kernels weigh the same as a cup of water?

A cup measures volume, not weight. Corn kernels is less dense than water (152 g versus 237 g per cup), so the same volume has a different weight. Weighing in grams is the most accurate way to measure it.
