Kale is a nutritional powerhouse, but if you track carbohydrates, knowing exactly what you're eating matters. This kale carbs per 100g calculator turns a handful of leaves or a cooked side dish into clear numbers: total carbohydrates, fiber, and net carbs per 100 grams — plus the same values for your exact serving.
The tool supports grams, ounces, cups of raw chopped kale, cups of cooked kale, and handfuls, so you can measure the way you actually eat. Choose raw or boiled kale and the calculator applies the appropriate nutrition data automatically. Quick-fill buttons make it easy to check common portions like 1 cup raw or 130 g cooked in one tap.
Whether you're meal prepping, following a low-carb or keto plan, or just curious how leafy greens fit into your daily macros, this calculator gives you fast, consistent answers.
🥬 Serving Amount
⚙️ Preparation
Cooked portions should be measured in grams or cups cooked.
How to Use This Calculator
Start by entering the amount of kale you plan to eat, using whichever unit matches how you actually measure it — grams, ounces, cups of raw chopped kale, cups of cooked kale, or raw handfuls. Next, pick the preparation state from the dropdown: raw kale or boiled/cooked kale. This matters because cooking changes both the weight of a given volume and the nutrient composition slightly, so the calculator applies a different data set for each form.
Once you press Calculate Carbs, the result panel shows three reference values per 100 g (total carbs, fiber, and net carbs) plus the same three values scaled to your exact serving, along with the estimated serving weight in grams. A step-by-step breakdown walks through the conversion so you can check the arithmetic yourself. If you want to start over, the Reset button clears the inputs and restores the default settings.
The Math Behind It
The calculator works in three steps. First, it converts your chosen unit into grams using fixed conversion factors: 1 ounce = 28.35 g, 1 cup raw chopped kale ≈ 21 g, 1 cup cooked kale ≈ 130 g, and 1 handful ≈ 25 g. Second, it scales the per-100 g nutrient values by the serving weight:
Fiber in serving = serving weight (g) × fiber per 100 g ÷ 100
Net carbs = total carbs − fiber
Net carbs are calculated for both the per-100 g reference values and for your specific serving. Because dietary fiber is not digested and absorbed like other carbohydrates, many low-carb and keto trackers subtract it from total carbs to get a more useful estimate of the carbs your body actually processes.
Worked Examples
Example 1 — 2 cups of raw kale. Two cups of raw chopped kale weigh about 42 g. Using raw kale values (8.75 g carbs and 3.6 g fiber per 100 g): total carbs = 42 × 8.75 ÷ 100 = 3.68 g; fiber = 42 × 3.6 ÷ 100 = 1.51 g; net carbs = 3.68 − 1.51 = 2.17 g.
Example 2 — 130 g of cooked kale. A typical cooked side serving weighs about 130 g. Using cooked values (8.8 g carbs and 4.1 g fiber per 100 g): total carbs = 130 × 8.8 ÷ 100 = 11.44 g; fiber = 130 × 4.1 ÷ 100 = 5.33 g; net carbs = 11.44 − 5.33 = 6.11 g.
Example 3 — 1 ounce of raw kale. One ounce equals 28.35 g. Total carbs = 28.35 × 8.75 ÷ 100 = 2.48 g; fiber = 28.35 × 3.6 ÷ 100 = 1.02 g; net carbs = 2.48 − 1.02 = 1.46 g.
These examples show how the same calculator handles different units: the per-100 g numbers never change, but the serving totals scale linearly with weight.
Reference Values: Kale Per 100 g
| Form | Total Carbs | Fiber | Net Carbs |
|---|---|---|---|
| Raw kale | 8.75 g | 3.6 g | 5.15 g |
| Boiled / cooked kale | 8.8 g | 4.1 g | 4.7 g |
Reference data based on the USDA FoodData Central entries for raw kale and boiled, drained kale. Actual values vary slightly by variety, growing conditions, and how thoroughly the kale is drained after cooking.
Tips & Common Mistakes
- Weigh raw before cooking. Cooked kale loses water, so a cooked cup contains far more leaf material than a raw cup and therefore more carbs by volume.
- Don't mix up cup types. A cup of raw chopped kale weighs about 21 g, while a cup of cooked kale weighs about 130 g. Using the wrong one changes the result by a factor of six.
- Remove thick stems before weighing if you don't eat them — they add weight but little nutrition.
- Be consistent with tracking. If your food diary uses cooked entries, log the cooked weight; if it uses raw entries, log the raw weight. Mixing them double-counts or undercounts carbs.
Frequently Asked Questions
Is kale actually low in carbs? Yes. A 100 g serving of raw kale contains about 8.75 g of total carbs and roughly 5 g of net carbs, which is modest compared with grains, legumes, and starchy vegetables. A typical cooked serving delivers even fewer net carbs per serving.
Why does cooked kale have different numbers? Boiling changes the weight of kale by replacing some volume with water and can slightly alter carbohydrate concentration. The USDA provides separate nutrient profiles for raw and cooked kale, and this calculator honors that distinction.
Where do the values come from? The nutrient data used here comes from the USDA FoodData Central database, a standard reference used by nutrition professionals. Values can shift a little between batches, so treat them as reliable estimates rather than laboratory-precise measurements.
Should I track total carbs or net carbs? It depends on your goals. Keto dieters usually track net carbs because fiber does not raise blood sugar; people managing diabetes often track total carbs because they need the full glucose impact. Either way, this calculator reports both.
