Why the ingredient matters
A cup is a volume, not a weight. Tomato passata has a density of 1.05 g/ml — different ingredients give different weights for the same cup. That's why generic « cup to gram » charts are wrong by 10–30 %.
How precise is this?
The density used here is sourced and cross-checked. Real-world measures still vary by about ±4% depending on how the cup is filled — sifted, scooped or packed.
