Tablespoons of dry breadcrumbs to grams runs on one number, 6.75 grams per tablespoon. It is a measured property of this ingredient rather than a defined conversion, which is why a generic volume-to-weight tool cannot give you it.
The density behind that figure is 0.45649 g per mL, against 1.00 for water. A cup of water weighs 236.6 g and a cup of dry breadcrumbs weighs 108 g, so this ingredient is 45.65% as heavy as the same volume of water — the single fact the whole page rests on.
A level tablespoon of dry breadcrumbs is 6.75 g, which puts a teaspoon at 2.25 g and a tablespoon and a half — the quantity recipes are fondest of — at 10.12 g. Levelling twice is where the error comes from, so the scale is the faster instrument once the quantity passes a couple of spoons.
Grams are the unit this conversion is really for. A domestic scale resolves to a gram, which is 0.926% of a cup of dry breadcrumbs, so weighing gets an accuracy no measuring cup can reach. A 500 g pack of it is 4.63 cups, and a 1 kg pack 9.259.
What the number depends on: Fine, dry and unseasoned. Fresh breadcrumbs weigh about half as much per cup because the crumb has not collapsed.
The formula
tablespoons- The amount of dry breadcrumbs you are converting, in tablespoons
6.75- Grams per tablespoon for dry breadcrumbs, from its density of 0.45649 g/mL
grams- The equivalent quantity in grams
How it works, step by step
- Enter the quantity in tablespoons.
- It is multiplied by 6.75, the grams-per-tablespoon figure for dry breadcrumbs.
- The result appears in grams, with a second reading in oz beneath it.
- Use the measure table if you want a standard recipe quantity rather than a number you type in.
Worked examples
2 tbsp of dry breadcrumbs in grams
Take 2 tbsp of dry breadcrumbs: 2 × 6.75 gives 13.5 grams. Doubling the batch takes it to 27 grams, because the relationship is a straight proportion once the density is known.
4 tbsp of dry breadcrumbs in grams
4 tbsp of dry breadcrumbs weighs out at 27 grams. Divide 27 by 6.75 and you get back to 4 tbsp, which is the quickest check that the factor is the right way up.
12 tbsp of dry breadcrumbs in grams
A recipe calling for 12 tbsp of dry breadcrumbs needs 81 grams on the scale. The arithmetic is 12 × 6.75 = 81, and halving the recipe halves the weight to 40.5 grams.

Frequently asked questions
How many grams are in 1 tbsp of dry breadcrumbs?
One tablespoon of dry breadcrumbs is 6.75 grams. Half that quantity is 3.375 grams and double it is 13.5 grams, so the figure scales straight up and down — there is no offset in this conversion, only the factor.
Why is a cup of dry breadcrumbs not 236 g like water?
Because weight per cup depends on what is in the cup. Dry breadcrumbs has a density of 0.45649 g per mL where water has 1.00, so a cup of it weighs 108 g rather than 236.6 g. That is a difference of 128.6 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 dry breadcrumbs by roughly 20% — about 10.8 g either side of 108 g — because fine, dry and unseasoned. Weighing removes the question entirely.
Is a fluid ounce of dry 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 dry breadcrumbs weighs 0.4762 oz, so the two readings differ by 52.4%. 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 dry breadcrumbs would weigh 114.12 g instead of 108 g — 6.12 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?
At this size the spoon wins. One tablespoon of dry breadcrumbs is 6.75 g, and a scale reading to the nearest gram is working at 14.8% resolution on that — a measuring spoon is the more accurate instrument below about 5 g, which is why spice quantities are still written in spoons.
How many tablespoons of dry breadcrumbs is 500 g?
500 g of dry breadcrumbs is 74.074 tablespoons — 0.148148 tablespoons to one gram, so 500 × 0.148148 = 74.074. Going that way is a division by 6.75, or a multiplication by 0.148148 if you prefer.
