Whether you’re tracking calories, building a meal plan, or simply curious about portion sizes, knowing how many calories are in 100g of noodles helps you compare foods on a level playing field. This calculator converts any amount of noodles — from a small ramen snack to a large pasta dinner — into a clear per-portion calorie and macro estimate.
Noodles vary widely: a cup of cooked pasta is not the same as a brick of dry instant ramen, and a bowl of shirataki noodles is dramatically lighter than one of udon. The tool includes common noodle types with typical dry and cooked values, lets you enter ounces as well as grams, and supports a custom calories-per-100g field when your package label differs from the presets.
Use the quick presets or type in your serving size, then hit Calculate to see calories plus carbs, protein, and fat for your exact portion.
Dry and cooked noodles differ a lot in weight and calories — always match your input to the state you are eating.
How It Works
The calculator uses the standard nutrition-label approach of expressing energy density as kilocalories per 100 grams. Each noodle preset stores a typical profile for calories, carbohydrates, protein, and fat per 100 g in a specified state, and the tool scales those values by the ratio of your portion to 100 g. If you enter ounces, it first converts to grams using 1 oz = 28.3495 g.
For example, if a noodle has 371 kcal per 100 g and your bowl holds 150 g, the estimate is 371 × 1.5 = 556.5 kcal. The result box also shows the per-100g breakdown so you can always see which base values were used.
Reference Data: Calories in Popular Noodles
The preset values are compiled from USDA FoodData Central entries and common package nutrition labels. Because recipes vary by brand, flour type, water content, and cooking time, treat these as typical figures rather than exact guarantees.
| Noodle type | kcal / 100 g | Carbs | Protein | Fat |
|---|---|---|---|---|
| Dry wheat pasta, uncooked | 371 | 74 g | 13 g | 2 g |
| Cooked wheat pasta | 131 | 25 g | 5 g | 1.3 g |
| Instant noodles, dry block | 452 | 60 g | 9 g | 20 g |
| Fresh ramen noodles, cooked | 138 | 25 g | 5 g | 2.1 g |
| Udon noodles, cooked | 120 | 25 g | 3 g | 0.4 g |
| Soba noodles, cooked | 99 | 21 g | 5 g | 0.4 g |
| Rice noodles, cooked | 109 | 24 g | 1.8 g | 0.2 g |
| Egg noodles, cooked | 138 | 25 g | 4.5 g | 2.1 g |
| Shirataki noodles, cooked | 10 | 3 g | 0.3 g | 0 g |
Dry vs. Cooked: Why It Changes Everything
Noodles absorb a large amount of water when boiled, so cooked noodles weigh more while carrying roughly the same calories as the dry form. For example, 100 g of dry wheat pasta contains about 371 kcal, but after cooking, 100 g of the same pasta drops to roughly 131 kcal because most of that weight is now water. Weighing your noodles in the same state as the nutritional reference — typically dry for dry pasta, cooked for fresh or instant brands — is the most reliable way to track.
Step-by-Step Guide
1. Pick the noodle type that matches what you are about to eat. 2. Enter the portion weight in grams or ounces, or tap a preset pill like “100 g” for quick input. 3. If your package label shows a different per-100g calorie figure, type it into the custom field and it will override only the calorie value. 4. Press Calculate to view calories, carbs, protein, and fat for your exact portion, plus the per-100g breakdown used in the math.
Frequently Asked Questions
Are calories the same for dry and cooked noodles? The total calories of the noodle itself barely change with cooking — water adds no calories — but the calories per 100 g change dramatically because the weight changes. Always match the state of your portion to the reference state.
How do I weigh noodles without a scale? You can use volume approximations (like 1 cup cooked spaghetti ≈ 140–150 g), but the most accurate results come from a kitchen scale. Nutrition tracking apps are most reliable when using weighed grams.
What about noodles made from alternative flours? Buckwheat, brown rice, edamame, and konjac noodles all have different energy densities. If your noodle is not listed, check the package for a per-100g value and enter it in the custom calories field.
Why does the calculator show macros too? Calories alone rarely tell the full picture. Having carbs, protein, and fat in the same tool helps with macronutrient targets, low-carb plans, and protein-focused meal prep, all without switching between apps.
