This calculator helps you determine the exact calorie content of cornmeal based on its weight in grams. Whether you're meal prepping, tracking macros, or following a recipe, knowing the calories per gram of cornmeal is essential for accurate nutrition planning.
Cornmeal is a staple ingredient in many cuisines, used for polenta, cornbread, tortillas, and more. Its calorie density varies slightly by grind type (fine, medium, coarse) and brand, but this tool uses standard USDA reference values to give you a reliable estimate. Simply enter the weight of your cornmeal in grams, and the calculator will instantly show the total calories, plus a breakdown per 10g and per 100g for easy scaling.
🌽 Cornmeal Calories Per Gram
How to Use This Tool
Using the Cornmeal Calories Per Gram Calculator is straightforward. Enter the weight of your cornmeal in grams (you can use decimal values for precision). Select the grind type — fine (like corn flour), medium (standard cornmeal), or coarse (polenta grits) — as each has a slightly different calorie density. Click the Calculate button to see the total calories, plus a breakdown per 10g and per 100g. Use the Quick Fill buttons for common weights like 1 ounce (28g), 50g, 100g, or 200g. The Reset button clears all fields and results.
Formula Explained
The calculation is based on the standard calorie density of cornmeal per gram, which varies slightly by grind type. The USDA National Nutrient Database provides the following reference values:
- Fine cornmeal (corn flour): 3.61 kcal per gram
- Medium cornmeal: 3.65 kcal per gram
- Coarse cornmeal (polenta grits): 3.57 kcal per gram
The formula is simple: Total Calories = Weight (g) × Calories per gram. For example, 100g of medium cornmeal yields 100 × 3.65 = 365 kcal. The per-10g and per-100g values are derived by multiplying the per-gram value by 10 or 100 respectively.
Worked Examples
Example 2: You use 80g of fine cornmeal for a gluten-free coating. Calories = 80 × 3.61 = 288.8 kcal. Per 10g: 36.1 kcal. Per 100g: 361 kcal.
Example 3: A recipe calls for 200g of coarse polenta grits. Calories = 200 × 3.57 = 714 kcal. Per 10g: 35.7 kcal. Per 100g: 357 kcal.
Factors Affecting Accuracy
While the USDA values are reliable, actual calorie content can vary slightly between brands due to differences in moisture content, processing methods, and added ingredients (e.g., enriched cornmeal may have small amounts of added vitamins but negligible calorie differences). For the most accurate tracking, check the nutrition label on your specific package. The values used here are averages and suitable for most diet planning purposes.
Real-World Applications
This calculator is useful for:
- Meal planning: Accurately count calories when using cornmeal in recipes like cornbread, polenta, or tortillas.
- Macro tracking: Cornmeal is primarily carbohydrate (about 76g carbs per 100g), so knowing the calorie content helps fit it into your daily macros.
- Recipe scaling: Easily adjust serving sizes by calculating the calories for any weight.
- Dietary management: Useful for weight loss, maintenance, or sports nutrition where precise calorie intake is important.

Frequently Asked Questions
Q: Does cooking change the calorie content of cornmeal?
A: No. Cooking adds water, which increases weight but not calories. The calorie content is based on the dry weight of the cornmeal. For example, 100g of dry cornmeal still contains 365 kcal even after cooking into porridge.
Q: Is cornmeal gluten-free?
A: Yes, pure cornmeal is naturally gluten-free. However, always check the label for cross-contamination if you have celiac disease.
Q: How does cornmeal compare to other grains?
A: Cornmeal is similar in calorie density to wheat flour (about 364 kcal/100g) but slightly lower than oat flour (404 kcal/100g). It is a good source of complex carbohydrates and provides some fiber.
Q: Can I use this calculator for masa harina?
A: Masa harina (used for tortillas) has a similar calorie density, around 3.6 kcal/g, so the fine grind setting is a reasonable approximation. For precise values, refer to the masa harina package.
