How Much Is 128 Grams of Raw Sugar in Teaspoons?
128 grams of raw sugar equals 30.72 tsp. Raw sugar has a density of 200g per cup. Because grams measure weight and teaspoons measure volume, the result depends on the ingredient's density.
Formula and Step-by-Step
- Start with 128 grams of raw sugar
- 1 cup of raw sugar = 200g
- 128g ÷ 200g/cup = 0.64 cups × 48 = 30.72 teaspoons
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Understanding the Units
What is a Gram?
A gram (g) is a metric unit of mass equal to 1/1000 of a kilogram. It is the standard weight measurement for precise baking worldwide. Professional bakers prefer grams because they are more accurate than volume measurements.
What is a Teaspoon?
A US teaspoon is 4.929 ml, a metric teaspoon is exactly 5 ml, and an imperial teaspoon is 5.919 ml. The metric and US versions are nearly identical (1.4% difference), but the imperial teaspoon is 20% larger. For most spices the difference is negligible, but for leaveners like baking powder it can affect the result.
