Black sugar — also called unrefined cane sugar, muscovado, or kokuto — is a darker, minimally processed sweetener that keeps some of the molasses and trace minerals found in sugarcane. Unlike white sugar, which is stripped and refined, black sugar retains small amounts of potassium, calcium, magnesium, and iron, which is why it is often used in Asian baking, teas, and traditional tonics. This black sugar per 100g calculator converts your portion into grams and shows how the nutrition per 100g scales to the amount you actually want to use.
Whether you are tracking calories, building a meal plan, comparing sweeteners, or trying to understand a nutrition label, this calculator gives you a fast, clear estimate. It works with whole grams, tablespoons, teaspoons, or cups, and it can even compare black sugar against white sugar so you can see the real difference. Use the quick-fill presets for common baking portions, then hit Calculate to see calories, carbs, sugars, and key minerals for any serving size.
Black Sugar Nutrition Calculator
Convert any portion into per-100g and serving nutrition.
Use 1 tbsp ≈ 13 g, 1 tsp ≈ 4.3 g, 1 cup ≈ 180 g.
How to Use This Tool
Start by entering your portion in the calculator card above. You can type any positive number, choose the unit that matches your recipe from the dropdown, or tap a quick-fill preset for common amounts. The calculator converts your portion to grams, then scales the per-100g nutrition values for black sugar.
If you want a quick comparison, leave the Compare with white sugar checkbox ticked. You can also keep Show step-by-step breakdown on to see exactly how each nutrient was scaled. This is especially helpful if you are adjusting a recipe and want to understand how the math works.
Tip: For dry black sugar, use a kitchen scale when possible. Volume measures like tablespoons and teaspoons are convenient, but they can vary by 10-15% depending on how tightly the sugar is packed.
How It Works
Black sugar is roughly 98% carbohydrate, most of which is sucrose, glucose, and fructose from the unrefined cane juice. The per-100g values used in this calculator are typical for commercially available unrefined cane sugar products such as muscovado, kokuto, or panela: 380 kcal, 98 g total carbs, 96 g sugars, 1100 mg potassium, 240 mg calcium, and 3.9 mg iron. These numbers are averages, and different brands can vary slightly because the mineral content depends on the soil and processing method.
The calculation is a simple proportion: nutrition per portion = nutrition per 100g × (portion grams / 100). If you enter 2 tablespoons, we first convert to grams using 1 tablespoon = 13 g, then apply the scale factor. For example, 13 g / 100 = 0.13, so every nutrient in a 13 g serving is 13% of the 100 g value.
Because black sugar is still an added sugar, most of its calories come from carbohydrates with no protein, fiber, or fat. The trace minerals are a nice bonus, but the sugar content is the main thing to account for when tracking your daily intake.
Worked Examples
Example 1: One tablespoon (13 g)
Scale factor = 13 / 100 = 0.13
Calories: 380 × 0.13 ≈ 49 kcal
Total carbs: 98 × 0.13 ≈ 12.7 g
Sugars: 96 × 0.13 ≈ 12.5 g
Potassium: 1100 × 0.13 ≈ 143 mg
Example 2: 50 g (about 1/4 cup)
Scale factor = 50 / 100 = 0.50
Calories: 380 × 0.50 = 190 kcal
Total carbs: 98 × 0.50 = 49 g
Sugars: 96 × 0.50 = 48 g
Potassium: 1100 × 0.50 = 550 mg
You can verify these numbers with the calculator by using the 13 g and 50 g presets.
Reference Data
| Nutrient | Per 100 g | Per 1 tbsp (13 g) |
|---|---|---|
| Calories | 380 kcal | 49 kcal |
| Total carbs | 98 g | 12.7 g |
| Sugars | 96 g | 12.5 g |
| Potassium | 1100 mg | 143 mg |
| Calcium | 240 mg | 31 mg |
| Iron | 3.9 mg | 0.5 mg |
For context, refined white sugar provides about 400 kcal and 100 g of carbs per 100 g, but contains nearly no potassium, calcium, magnesium, or iron. That means the mineral differences are small in typical serving sizes, although black sugar can still add useful amounts when used consistently in baking or beverages.
Common Mistakes to Avoid
- Using packed and loose volume interchangeably. A tablespoon of loosely scooped black sugar can weigh 10-11 g, while a packed tablespoon can weigh 14-15 g. If you need precision, weigh it.
- Assuming black sugar is a free food. It is still added sugar and contributes calories. The World Health Organization and the American Heart Association both recommend limiting added sugars, including unrefined types.
- Expecting fiber. Black sugar contains no significant dietary fiber, so it should not be counted as a whole grain or high-fiber food.
- Overlooking the sugar content. Even though it has minerals, the 12.5 g of sugar in one tablespoon is very similar to white sugar's 12.6 g, so portion control still matters.
Frequently Asked Questions
Is black sugar healthier than white sugar?
Black sugar retains small amounts of minerals that white sugar lacks, but the difference is modest. A 13 g serving provides roughly 143 mg of potassium and 31 mg of calcium, which is less than a small bite of a potato or a splash of milk. It is not a meaningful source of micronutrients compared with whole foods, but it is a slightly less processed sweetener.
How many grams are in a tablespoon of black sugar?
For this calculator we use 13 g per tablespoon, which is the average for dry, moderately packed black sugar. A lightly packed tablespoon may be closer to 11 g, and a tightly packed one may be 15 g.
Does black sugar spike blood sugar the same as white sugar?
Broadly, yes. Black sugar is still mostly sucrose and has a glycemic index similar to white sugar, usually in the 60-65 range. If you are tracking carbs or managing blood glucose, use the carbohydrate numbers from this calculator rather than assuming it behaves differently.
Can I substitute black sugar in recipes that call for brown sugar?
Yes. Black sugar swaps roughly 1:1 with brown sugar or muscovado, though it may have a deeper, slightly more molasses-like flavor. You can adjust liquid slightly if the sugar is drier than your usual brand.
If you are tracking total sugar intake, you may also want to check the sugar calories per serving calculator for refined sugar, or the added sugar limit calculator to see how your daily use fits into health guidelines.
