Why Your Cup of Fresh Grapefruit Juice Might Weigh Differently
Understanding key volumetric variables prevents measuring errors when converting recipes to scale weights in grams.
Compaction & Particle Headspace
Scooping fresh grapefruit juice 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 (246g), a US Legal cup holds 240ml (250g), and a Metric cup holds 250ml (260g). Misidentifying cup capacity alters recipe scale mass by up to 6 percent.
Atmospheric Moisture & Settling
Granular particles of fresh grapefruit juice absorb ambient humidity during storage, increasing bulk density and scale readout per cup portion.
