}Explanation
Use the same 80 g per US cup reference to express onion powder weight as US cups.
Gram-based recipes and cup-based prep therefore use one explicit assumption. That is especially useful for rubs, spice blends, and recipe scaling where small spoon measures add up quickly. Very small gram amounts are too little to measure reliably in a cup, so cup measuring only becomes practical at larger weights. Onion Powder can vary with grind size and how loosely it fills a spoon or cup, so the page keeps one fixed basis for repeatable reference use.
