Why panko breadcrumbs needs its own conversion
Panko Breadcrumbs weighs about 50g per cup — quite light and airy compared to many kitchen staples. King Arthur Japanese Panko = 50 g/cup; much airier than standard dried breadcrumbs. A cup is a unit of volume, so ingredients this different in density can't share one generic conversion factor — using a single "1 cup = X g" rule for everything will be wrong for at least some of what you cook.
Common measurement mistakes
- Using a generic cup-to-gram factor for every ingredient — panko breadcrumbs does not weigh the same per cup as most other ingredients.
- Measurement note: King Arthur Japanese Panko = 50 g/cup; much airier than standard dried breadcrumbs.
- Confusing weight ounces with fluid ounces when a recipe lists "oz" — they are not interchangeable.
