How the Powdered Sugar Converter Works
The Powdered Sugar Converter divides powdered (confectioners) sugar mass by its bulk density. The default 0.56 kg/L fits sugar scooped from the bag.
Choose the method
Sifted, spooned, scooped and packed powdered sugar differ by up to 55% in density.
Pick the density
Use 0.44 kg/L sifted, 0.51 kg/L spooned, 0.56 kg/L scooped or 0.68 kg/L packed.

Convert liters to cups for frosting recipes.
Powdered Sugar Converter Formula
The powdered sugar formula is V = m ÷ ρmethod. Sifting adds air and drops density by about 21% against scooping.
- ρmethod
- Bulk density for the filling method, kg/L
Worked Examples
- Sifted for icing: 250 g ÷ 0.44 = 568 mL (2.40 cups).
- Scooped: 250 g ÷ 0.56 = 446 mL.
- 1 lb (454 g) box, spooned: 454 ÷ 0.51 = 890 mL (3.76 cups).
Powdered Sugar Converter Conversion Table
1 US cup of sifted powdered sugar weighs about 104 g, against 132 g scooped. The table lists 5 measuring methods.
| Measuring Method | Density (kg/L) | Grams per US cup | Grams per tbsp | Liters per 1 kg |
|---|---|---|---|---|
| Sifted | 0.440 | 104 | 6.5 | 2.273 |
| Spooned and leveled | 0.510 | 121 | 7.5 | 1.961 |
| Scooped from bag | 0.560 | 132 | 8.3 | 1.786 |
| Tapped | 0.620 | 147 | 9.2 | 1.613 |
| Packed | 0.680 | 161 | 10.1 | 1.471 |
What is a Powdered Sugar Converter?
A Powdered Sugar Converter is a calculator that converts confectioners sugar weight into volume using a density matched to sifting or packing.
Powdered sugar is granulated sugar milled into a fine powder. US 10X powdered sugar contains about 3% cornstarch to stop caking; icing sugar in the UK often contains none.
Fine particles trap a lot of air and pack unevenly. Weighing powdered sugar gives the most repeatable frosting texture.
