How many grams are in 1 cup of panko?

One cup of panko breadcrumbs weighs about 50 grams. Panko is flaked and airy, so it weighs much less per cup than dense, finely ground breadcrumbs.

Does panko weigh the same as regular breadcrumbs?

No. Regular dry breadcrumbs are finer and more tightly packed, so a cup of them weighs about 108 grams, roughly double the weight of a cup of panko.

Why does my panko weight not match the package label?

Brands flake and dry panko to slightly different textures, so package-listed weights can differ from this chart by a few grams per cup. For best results, weigh against the specific brand you are using when a recipe is weight-sensitive.

Is it better to measure panko by weight or by cups?

By weight. Panko flakes settle and compress differently depending on how a cup is filled, while a gram measurement stays consistent every time, which matters most for a coating ratio.

How many grams is 1/3 cup of panko?

One-third cup of panko is about 17 grams, based on the 50 g per cup density used throughout this tool.

Can I substitute panko for regular breadcrumbs by weight?

Yes, weight is the more reliable way to substitute. Swapping by cup volume alone will use less panko by weight than the breadcrumbs it replaces, since panko is lighter and airier.

Summary

Panko is coarser and airier than regular dry breadcrumbs, so a cup of it weighs noticeably less than a cup of fine crumbs. This tool converts between US cups and grams using panko's lighter density, updates as you type, and includes a reference chart for the amounts that show up most often in recipes.

Use cases

Scale a fried chicken, katsu, or tonkatsu recipe that lists panko in cups onto a kitchen scale.
Convert grams from a recipe or product label into US cup measurements for panko.
Check how many grams are in 1/2 cup of panko before coating a cutlet or fish fillet.
