Ounces here are ounces of weight (1 oz = 28.35 g), not fluid ounces. One US cup is 8 fluid ounces of volume whatever is in it, but what it weighs in ounces depends on the ingredient: a cup of panko breadcrumbs weighs about 1.76 oz. Why these two are not the same.
In grams, 1/4 cup of panko breadcrumbs is about 13 g, 1/3 cup is about 17 g, 1/2 cup is about 25 g, 2/3 cup is about 33 g, 3/4 cup is about 38 g, 1 cup is about 50 g, 1 1/2 cups is about 75 g, 2 cups is about 100 g and 3 cups is about 150 g.

About measuring panko breadcrumbs
Panko is a Japanese-style breadcrumb made from crustless bread, dried into large airy flakes rather than fine crumbs, so one US cup weighs only about 50 grams, less than half the weight of regular dry breadcrumbs. That extra air is exactly what gives panko its signature crunch when fried or baked, since the flakes stay crisp instead of packing into a dense coating. Because it is so light, a recipe written for regular breadcrumbs will need noticeably more panko by volume to match the same weight.
Panko is about half the weight of regular dry breadcrumbs per cup, so swap by weight, not by cup for cup.
How many grams is a cup of panko breadcrumbs?
One US cup (240 ml) of panko breadcrumbs weighs about 50 grams. Because a cup measures volume rather than weight, that figure is specific to panko breadcrumbs and does not transfer to any other ingredient: the same cup holds 125 grams of all-purpose flour and 340 grams of honey.
- 1/4 cup of panko breadcrumbs is about 13 grams
- 1/3 cup of panko breadcrumbs is about 17 grams
- 1/2 cup of panko breadcrumbs is about 25 grams
- 2/3 cup of panko breadcrumbs is about 33 grams
- 3/4 cup of panko breadcrumbs is about 38 grams
- 1 1/2 cups of panko breadcrumbs is about 75 grams
- 2 cups of panko breadcrumbs is about 100 grams
- 3 cups of panko breadcrumbs is about 150 grams
Working the other way round, 100 grams of panko breadcrumbs is about 2 cups, and 500 grams is about 10 cups.
Does it matter which cup my recipe means?
It does, though less than the ingredient itself. This page uses the US legal cup of 240 ml. An Australian metric cup is 250 ml, so a metric cup of panko breadcrumbs comes to about 52 grams, and the old British imperial cup of 284.1 ml holds about 59 grams.

Frequently asked questions
How many grams is 1 cup of panko breadcrumbs?
One US cup of panko breadcrumbs is about 50 grams. The large, airy flakes hold a lot more air than fine dry breadcrumbs.
Why is panko lighter than regular breadcrumbs?
Panko is made from crustless bread dried into big flakes rather than ground fine, so a cup traps far more air. A cup of regular dry breadcrumbs is about 108 grams, more than double the weight of panko.
Can I substitute panko for regular breadcrumbs?
Yes, but match them by weight rather than by cup measure, since panko is much lighter by volume. Panko also gives a crisper coating than fine dry breadcrumbs.
Where this figure comes from
We have not yet found a published reference that states a weight for a cup of panko breadcrumbs. The 50 grams on this page follows the calibration the rest of the site is built on, with butter at 227 grams per cup, water at 240, all-purpose flour at 125 and granulated sugar at 200. Treat it as a good working figure rather than a cited one. If you have a better source, tell us and we will check it and credit you.
Published figures for the same ingredient vary between references anyway, because how an ingredient is packed changes what a cup of it weighs. Treat any cup figure as accurate to within a few percent, and weigh on a scale when a recipe is sensitive. Our full approach is on the methodology page.
