Why Your Cup of Superfine Caster Sugar Might Weigh Differently
Understanding key volumetric variables prevents measuring errors when converting recipes to scale weights in grams.
Compaction & Particle Headspace
Scooping superfine caster sugar directly compresses air voids between granules, cramming up to 15 percent extra mass into the same cup volume.
Regional Cup Standard Variance
A US Customary cup holds 236.59ml (200g), a US Legal cup holds 240ml (203g), and a Metric cup holds 250ml (211g). Misidentifying cup capacity alters recipe scale mass by up to 6 percent.
Atmospheric Moisture & Settling
Granular particles of superfine caster sugar absorb ambient humidity during storage, increasing bulk density and scale readout per cup portion.
