How this works
Powdered sugar has a density of about 0.478 g/mL (king arthur baking: 1 cup = 113g). That means 1 mL of powdered sugar weighs 0.478 grams.
Teaspoons = ounces × 12.0328
Note: Unsifted; sifted is closer to 0.42 g/mL.
Why a cup of powdered sugar doesn't always weigh the same
Volume measurements are forgiving in some ways and brutal in others. A cup of powdered sugar can vary by 10-20% in weight depending on how it's measured: spooned vs scooped, packed vs loose, sifted vs unsifted. The density figure used here (0.478 g/mL) matches the most common published recipe conventions, but if you're after baking precision, weighing on a kitchen scale is more accurate than measuring by volume.

Volume vs weight in cooking
The American convention of measuring ingredients by volume (cups, tablespoons, teaspoons) is convenient but introduces variability that doesn't exist in weight-based recipes. Most professional bakers and bakeries weigh ingredients to within a gram because the structure of baked goods depends on precise ingredient ratios. For everyday cooking — soups, sauces, sautés — the volume-to-weight imprecision rarely matters. For baking that depends on rising or texture (cakes, breads, laminated doughs), it matters a lot.
The conversion
Multiplying the volume of powdered sugar by its density (0.478 g/mL) gives the weight in grams. The calculator at the top of this page does the math automatically; the formula box above shows the resulting linear factor for the specific volume and weight units selected here.
