Key Facts about Granulated Sugar
Calories & Carbohydrates
1 teaspoon (4.2 g) of granulated sugar delivers approximately 16 calories and 4.2 grams of carbohydrates.
Powdered vs. Granulated
Powdered sugar contains cornstarch and fine aeration, weighing only ~2,760 mg per tsp, whereas packed brown sugar is denser (~4,580 mg).
Daily Sugar Guidelines
The AHA recommends a daily added sugar maximum of 25,000 mg (6 tsp / 25 g) for women and 36,000 mg (9 tsp / 36 g) for men.
How to Convert a Teaspoon of Granulated Sugar to Milligrams
Teaspoons measure volume. Milligrams measure mass. To convert between them you need the substance density.
For Granulated Sugar, the density is approximately 0.845 g/mL. Granulated white sugar density is approximately 0.845 g/mL. 1 US tsp = ~4,165 mg.
Formula
mg = tsp × 4.92892 mL × 0.845 g/mL × 1000Example: 1 tsp of Granulated Sugar = 1 × 4.92892 × 0.845 × 1000 = 4,164.94 mg
Methodology and density source
Density is a representative reference value. Product labels or manufacturer specifications should take priority when available.
The calculation uses the stated 0.845 g/mL density and the selected teaspoon standard. It does not infer a nutritional serving size or a medical dose.
For measurement definitions, see the teaspoon-to-milligram methodology.
Accuracy limitations
This is an estimate: spoon level, packing, particle size, moisture, temperature, and density can change the result.
Use a calibrated scale when the result matters. Level the spoon and identify whether the ingredient is loose, sifted, or packed.
