Why sources disagree

Panko flakes are large and airy, so a cup weighs about half as much as fine dried bread crumbs, which are 108 g per cup by USDA. That is why swapping panko for regular crumbs by volume gives a lighter coating. The 10 g gap between the sources comes down to how loosely the flakes settle in the cup. Panko is made from wheat flour.

How to measure panko bread crumbs accurately

Spoon panko into the cup and level it without pressing the flakes down.
Weigh panko when swapping it for regular dried bread crumbs, since a cup of each weighs very differently.
Weigh on a digital scale when you can, since cup scoops vary from cook to cook.

Convert the whole recipe, not one line

Converting a recipe one ingredient at a time is where mistakes slip in. Sous Chef imports a recipe from a link or pasted text, then converts every ingredient at once: dry ingredients and butter to grams, liquids to millilitres. Tap again to go back to cups.

US recipe

2¼ cups all-purpose flour

1½ cups milk

In Sous Chef, after "Convert to metric"

275 g all-purpose flour
225 g butter, softened
170 g brown sugar, packed
350 ml milk

Example output. Sous Chef rounds to amounts you would actually weigh, so its numbers can differ by a few grams from the table above.

Can I swap panko for regular bread crumbs cup for cup?
