What affects the calorie value
White granulated sugar is almost entirely carbohydrate. The selected record provides 387 kcal per 100 g, while a 4.2 g teaspoon provides about 16 kcal.
A heaped spoon can weigh considerably more than a level reference teaspoon. For baking and preserves, weigh the total sugar and calculate the final recipe yield.
Vitamins and minerals per 100 g
Values come from the same USDA records. They show the amount in the food, not a percentage of an individual daily requirement.
| Nutrient | White granulated sugar |
|---|---|
| Calcium, mg | 1 |
| Potassium, mg | 2 |
| Iron, mg | 0.05 |
| Selenium, µg | 0.6 |
| Sodium, mg | 1 |
How to calculate more accurately
For a spoonful or cube, use the package weight or weigh it. Level and heaped spoons hold different amounts.
The 5 g and 10 g servings are calculation shortcuts, not universal teaspoon or tablespoon capacities.
USDA lists 387 kcal per 100 g for this record. Labels may show around 400 kcal due to calculation and rounding methods; use your brand label when available.
Common questions
Calories in 10 g of sugar?
This reference gives 38.7 kcal. Sugar weight matters more than spoon size.
How many calories are in a teaspoon of sugar?
A level 4.2 g teaspoon provides about 16 kcal. Actual weight depends on how the spoon is filled.
How many calories are in a tablespoon of sugar?
The exact tablespoon weight depends on whether it is heaped. At 12.6 g it provides about 49 kcal, but weighing is better for a precise recipe.
Does sugar contain meaningful vitamins and minerals?
Amounts are very small in the selected record. The table shows reference trace values and does not make sugar a meaningful micronutrient source.
