How do I scale the original portion?

Start with 113 g per 1 cup. Multiply that gram amount by the requested number of source portions. The generated amount table uses the same calculation as the converter; displayed results are rounded only at the end.

Can I convert milliliters of powdered sugar (unsifted) to grams here?

No independently verified density is available for this ingredient in this release. Cup/spoon reference weights cannot establish one without a verified source cup volume. Volume-to-volume and grams-to-ounces conversions still work.
