One gram of panko breadcrumbs is 0.016666667 cups, so converting grams of panko breadcrumbs to cups means multiplying by 0.016666667. That factor is specific to this ingredient — it comes from its density, not from any relationship between the two units.
Put next to water — 1 g per mL exactly — panko breadcrumbs measures 0.25361 g per mL. That ratio, 25.36%, is what separates this page from every other ingredient in the same units, and it is measured rather than defined.
A cup of panko breadcrumbs is 60 g when it is measured the standard way, but how it gets into the cup changes the answer: between about 54 g and 72 g covers the range from lightly spooned to firmly packed. That 20% spread is larger than most of the adjustments recipes fuss over, and it disappears entirely the moment the ingredient is weighed instead.
Grams are the unit this conversion is really for. A domestic scale resolves to a gram, which is 1.67% of a cup of panko breadcrumbs, so weighing gets an accuracy no measuring cup can reach. A 500 g pack of it is 8.333 cups, and a 1 kg pack 16.67.
The condition this weight assumes: The lightest crumb there is. The flakes are large and mostly air, which is exactly what keeps a coating crisp.
The formula
grams- The amount of panko breadcrumbs you are converting, in grams
0.0166666666667- Cups per gram for panko breadcrumbs, from its density of 0.25361 g/mL
cups- The equivalent quantity in cups
How it works, step by step
- Enter the quantity in grams.
- It is multiplied by 0.0166666666667, the cups-per-gram figure for panko breadcrumbs.
- The result appears in cups, with a second reading in tbsp beneath it.
- Use the measure table if you want a standard recipe quantity rather than a number you type in.
Worked examples
50 g of panko breadcrumbs in cups
50 g of panko breadcrumbs weighs out at 0.833333 cups. Divide 0.833333 by 0.016666667 and you get back to 50 g, which is the quickest check that the factor is the right way up.
150 g of panko breadcrumbs in cups
150 g of panko breadcrumbs weighs out at 2.5 cups. Divide 2.5 by 0.016666667 and you get back to 150 g, which is the quickest check that the factor is the right way up.
500 g of panko breadcrumbs in cups
Take 500 g of panko breadcrumbs: 500 × 0.016666667 gives 8.33333 cups. Doubling the batch takes it to 16.6667 cups, because the relationship is a straight proportion once the density is known.

Frequently asked questions
How many cups are in 1 g of panko breadcrumbs?
One gram of panko breadcrumbs is 0.016666667 cups. Half that quantity is 0.00833333 cups and double it is 0.0333333 cups, so the figure scales straight up and down — there is no offset in this conversion, only the factor.
Why is a cup of panko breadcrumbs not 236 g like water?
Because weight per cup depends on what is in the cup. Panko breadcrumbs has a density of 0.25361 g per mL where water has 1.00, so a cup of it weighs 60 g rather than 236.6 g. That is a difference of 176.6 g per cup, and it is the reason a single volume-to-weight factor cannot be applied to every ingredient.
Does how I measure it change the weight?
Yes, and by more than most people expect. Handling changes the weight of a cup of panko breadcrumbs by roughly 20% — about 6 g either side of 60 g — because the lightest crumb there is. Weighing removes the question entirely.
Is a fluid ounce of panko breadcrumbs the same as an ounce?
No. A fluid ounce is a volume — one eighth of a US cup, 29.57 mL — and an ounce is a weight. One fluid ounce of panko breadcrumbs weighs 0.2646 oz, so the two readings differ by 73.5%. They coincide only for something with the density of water, and then only roughly.
Is this a US cup or a metric cup?
US customary: 236.59 mL, which is the cup every US recipe means. A metric cup is 250 mL, so the same cup of panko breadcrumbs would weigh 63.401 g instead of 60 g — 3.4 g more, or 5.67%. Australian and some European recipes use the metric cup, and the difference is large enough to matter in baking.
Do I need a scale for this, or will measuring cups do?
A scale, if the result matters. Volume measuring carries a spread of about 20% for panko breadcrumbs — roughly 12 g on a 60 g cup — while a domestic scale is accurate to a gram or two. For anything where the ratio of ingredients drives the outcome, bread and pastry above all, weigh it.
How much does 2 cup of panko breadcrumbs weigh?
2 cup of panko breadcrumbs comes to 120 g, or 120 grams. This page runs that calculation in reverse — enter a weight and it returns the volume — and the cups-to-grams page does it in the direction the question is usually asked.
