Compaction & Particle Headspace
Scooping air-popped plain popcorn 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 (8g), a US Legal cup holds 240ml (8g), and a Metric cup holds 250ml (8g). Misidentifying cup capacity alters recipe scale mass by up to 6 percent.
Atmospheric Moisture & Settling
Granular particles of air-popped plain popcorn absorb ambient humidity during storage, increasing bulk density and scale readout per cup portion.
