How it is calculated
grams = amount × unit size in US cups × 113. 1 tbsp = 1/16 cup, 1 tsp = 1/48 cup, metric cup 250 mL = 1.0567 US cups. 1 oz = 28.3495 g.
Example
Inputs: Amount = 0.5, Unit = US cup (236.6 mL). Result: Weight in grams: 56.5 g; Weight in ounces: 1.99 oz.
Limits and caveats
- The figure is for unsifted powdered sugar; sugar sifted before measuring weighs less per cup.
- Chart figures are rounded to the gram, and a scale is more exact than any cup.
- Metric cup (250 mL) and spoon values are scaled by volume from the 236.59 mL US cup figure.
Questions about this tool
How many grams is 1/2 cup of powdered sugar?
Half a US cup is 56.5 g, because a full cup is 113 g in the chart; a quarter cup is 28.3 g.
Should I sift powdered sugar before measuring?
The 113 g figure is for unsifted sugar. Sifting first makes the cup lighter, so sift after measuring if the recipe asks for it.
Why do cup weights differ between websites?
Charts assume different ways of filling the cup. This tool uses the King Arthur Baking ingredient weight chart: 1 cup of unsifted powdered (confectioners') sugar = 113 g (4 oz).
