1/3 Cup Breadcrumbs in Grams
1/3 cup of breadcrumbs weighs 37.3 g (spooned and levelled, King Arthur Baking). That single number is the whole point of this page, but the reason it matters is that cups measure volume and recipes live or die by weight. Breadcrumbs is one of those ingredients where a cup can hide a surprisingly wide range of weights, so converting to grams takes the guesswork out. Every figure on this page is approximate and comes from the King Arthur Baking value for breadcrumbs, so when a recipe really matters, verify with a kitchen scale.
Why weighing breadcrumbs beats scooping it
Breadcrumbs is the kind of ingredient where the cup method quietly fails. A cup is a volume measure, and the weight of a volume depends on how tightly the ingredient is packed, how fine it is, and even how humid the kitchen is. Two people filling the same cup of breadcrumbs can easily end up with weights several grams apart, and in a recipe that calls for 1/3 cup, that difference doubles. Grams remove the variable entirely: 37.3 g of breadcrumbs is 37.3 g of breadcrumbs in any kitchen, on any day, in any hands. That is why professional recipes are written in grams, and why converting your cup measurements is the single cheapest upgrade you can make to your cooking. You do not need expensive equipment — a basic digital scale that reads to the gram costs less than a bag of good flour and pays for itself the first time a cake comes out right.

The tablespoon column is a bonus for recipes that call for a spoonful or two: one tablespoon of breadcrumbs weighs about 7 g. Remember that a cup is 16 tablespoons, so the numbers in the table are just the cup weight divided by 16, rounded sensibly. For small amounts a scale that reads to the gram is far more reliable than a spoon, because a heaped tablespoon can weigh half as much again as a level one.
How the weight was measured
Spooned and levelled means the ingredient was measured the way King Arthur Baking measures it: spooned into the measuring cup until heaped, then levelled with a straight edge. Never scoop the cup through the bag or jar, and never tap the cup down, because both pack the ingredient and add weight. The source for the 112 g per cup figure is King Arthur Baking, and the confidence in the value is high. King Arthur Baking publishes a standard ingredient weight chart that recipe developers use as a reference, and this page follows it exactly rather than averaging across sources, because an average of two different measuring methods is a number that matches nobody's cup.
Worked examples
A breading station for fried chicken
A breading station for a family pack of chicken often uses 1/3 cup of breadcrumbs, which is 37.3 g. Weigh it into a shallow dish and you know exactly how much coating you have; when it runs low, weigh out a fresh half-batch rather than topping up by eye. Even coating means even crunch.
A sauce that needs thickening
A sauce recipe calling for 1/3 cup of breadcrumbs needs 37.3 g. Adding it gradually and whisking as you go is the safe route: you can always add more, but you cannot take it out. Weigh the full amount first, then add it in two or three stages until the sauce coats the back of a spoon.
Meal prep for the week
Cooking in bulk is where weighing earns its keep. A week of lunches built around 1/3 cup of breadcrumbs starts with 37.3 g measured once, and the portions come out identical across five containers. That consistency is what makes meal prep actually work instead of turning into five slightly different meals.
Common mistakes with breadcrumbs
The most common mistake is scooping the cup through the container instead of spooning and levelling. Scooping packs the ingredient and can add 10 to 20 percent extra weight — enough to ruin a bake. The second mistake is using a liquid measuring jug for a dry ingredient, or a dry cup for a liquid: the two are calibrated differently and the meniscus on a jug is hard to read at 1/3 cup. The third mistake is forgetting to tare the scale, so the weight of the bowl gets counted as ingredient. Put the bowl on the scale, press tare so the display reads zero, and then add the ingredient. Finally, do not trust a cup that has been sitting in a humid kitchen: breadcrumbs absorbs moisture from the air, and a cup weighed on a damp day is heavier than the same cup on a dry day. The scale does not care about humidity — it tells you what is actually there.
Frequently asked questions
How many grams is 1/3 cup of breadcrumbs?
1/3 cup of breadcrumbs weighs approximately 37.3 g, measured spooned and levelled. The figure comes from the King Arthur Baking value of 112 g per cup. All weights on this page are approximate — verify with a kitchen scale when precision matters.
Can I use a cup instead of weighing breadcrumbs?
Yes, but spoon and level rather than scooping: spoon breadcrumbs into the cup until heaped, then sweep a knife across the top. Scooping packs the ingredient and can add 10 to 20 percent extra weight. For 1/3 cup, fill and level the cup twice. Weighing 37.3 g is more accurate and, once you are used to it, faster.
Is 37.3 g exact for 1/3 cup of breadcrumbs?
No — it is approximate. The per-cup value of 112 g comes from King Arthur Baking, and real-world variation in brand, grind, moisture and packing means your cup may weigh a few grams more or less. For most cooking that is fine; for baking, weigh with a scale and treat the table as your planning guide.
How many cups is 37.3 g of breadcrumbs?
37.3 g of breadcrumbs is 1/3 cup — the conversion works in both directions, since 112 g equals one cup. If your recipe is written in grams and your tools are cups, divide the gram weight by 112 to get cups.
How do I measure breadcrumbs without a scale?
Use the spoon-and-level method: spoon breadcrumbs into a dry measuring cup until it is heaped above the rim, then level it with the back of a knife. Do not scoop the cup through the bag and do not tap it down. For 1/3 cup, repeat for a second cup. It is less accurate than weighing 37.3 g, but it is the best cup method available.
