Why Your Cup of Air-Popped Plain Popcorn Might Weigh Differently

Understanding key volumetric variables prevents measuring errors when converting recipes to scale weights in grams.

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.
