How Much Is 640 Grams of Granulated Sugar in Teaspoons?
Converting 640 grams of granulated sugar to teaspoons gives 153.60 tsp. Divide by the density of granulated sugar (200g per cup). Each ingredient fills a different volume at the same weight.
Formula and Step-by-Step
- Start with 640 grams of granulated sugar
- 1 cup of granulated sugar = 200g
- 640g ÷ 200g/cup = 3.2 cups × 48 = 153.60 teaspoons
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Sugar is one of the easier dry ingredients to measure by volume because the crystals pack relatively consistently compared to flour or cocoa powder.

Understanding the Units
What is a Gram?
Grams are the preferred unit in professional kitchens and bakeries because they allow exact recipe scaling. To double a recipe, simply double the gram values. No need to worry about how tightly an ingredient is packed into a cup.
What is a Teaspoon?
In baking, teaspoon measurements are critical for ingredients where precision changes the outcome. Too much baking soda (1 tsp = 6g) creates a metallic taste, while too little means flat results.
