Corn converter: whole ears of corn, cups, grams

A recipe calls for 1 cup of corn kernels but you have whole ears to shuck. A medium ear yields around 105 g of cut kernels (about 0.68 cups), so the count shifts with ear size. This converter moves between whole ears of corn, chopped cups, grams, ounces, and pounds.

A small ear gives about 75 g of kernels and a large one around 135 g, so six ears in a chowder or salsa can swing the corn by a few hundred grams. Getting the size right keeps corn-heavy dishes on target.

Corn varieties and best uses

The conversions above are the same whatever variety you use; the difference is what each is good for. Here is how the common corn varieties compare.

VarietyBest for
Yellow SweetEveryday grilling, boiling, and corn salads: firm kernels and a classic sweet flavour that holds up well to heat.
White SweetRaw salads and lighter side dishes: sweeter and more tender than yellow, with a delicate flavour.
Bi-ColorAn all-round option for any cooking method: a mix of yellow and white kernels in one cob.
Baby CornStir-fries, noodle dishes, and Asian-style cooking: eaten whole, cob included, with a mild crunch.

Which should I pick?

For everyday grilling, boiling, and summer salads, Yellow Sweet is the standard choice: widely available, reliably sweet, and sturdy enough for the BBQ. White Sweet delivers a sweeter, more tender bite and suits raw eating and lighter salads. Bi-Color (Sugar and Butter) is the all-purpose pick when you want both in one cob. Baby Corn suits stir-fries and Asian dishes where the whole small cob goes in.

Frequently Asked Questions

What is the size of a medium ear of corn?
A medium ear of corn weighs about 105 g, which works out to roughly 0.68 cups (0.71 US cups) of chopped flesh. Ears of corn come in a range of sizes depending on the season, variety and where they were grown, so weight and cup figures shift accordingly. Use the size selector above to match what you actually have, then read the exact conversion for any amount.
How much does a medium ear of corn weigh?
A medium ear of corn weighs about 105 g, with a small one around 75 g and a large one near 135 g. That range changes the weight of any recipe that counts ears of corn by the piece, so set the size selector to match what you actually have before trusting a cup or gram figure.
How much does an average ear of corn weigh?
An average ear of corn is the same as a medium one: about 105 g. A small ear of corn is lighter at around 75 g and a large one heavier at about 135 g, so the size you actually have changes the total for any recipe that counts ears of corn by the piece rather than by weight.
How much does a large ear of corn weigh?
A large ear of corn weighs about 135 g, noticeably more than a medium, or average, one at 105 g or a small one at 75 g. Set the size selector to large to convert cups, grams and ounces for the bigger ears of corn you actually have on the counter.
How do I convert grams to ounces for any ingredient?
Converting grams to ounces is pure weight maths that applies to any food, not just ears of corn, so 200 grams is always 7.05 ounces. For other amounts, the weight converter at the link below handles grams, ounces, pounds, kilograms and stone in both directions. Grams to ounces converter
