This calculator converts granulated sugar between tbsp and g. The default example is 1 tbsp ≈ 12.375 g, using 198 g per US cup.
The default uses King Arthur Baking's “Sugar (granulated white)” entry, scaled to 198 g per cup. The chart weights are rounded baking references, not exact densities.
Packing, grinding, moisture and brand can change the weight that fits in a cup. For repeatable baking, weigh the ingredient. US customary measures are used: 1 cup = 16 tablespoons = 48 teaspoons = 236.5882365 mL.
The formula
cups = grams ÷ grams per cup
grams per cup- The editable density and packing assumption
US cup- 236.5882365 mL; a US butter stick is treated as half a cup
How to use this calculator
- Enter the quantity in tbsp.
- Check or replace the grams-per-cup assumption.
- Convert the source quantity to grams, then from grams to the target unit.
Worked examples
Default assumption
1 tbsp gives about 12.375 g at 198 g per cup. Changing the weight assumption changes the answer.
Frequently asked questions
Why is the answer an estimate?
Volume measures space; mass measures weight. Converting between them requires ingredient density, and that changes with packing and preparation.
Are fluid ounces and ounces interchangeable?
No. A fluid ounce measures volume; an avoirdupois ounce measures mass. This calculator keeps the two units separate.
