Teaspoons of dry breadcrumbs to grams runs on one number, 2.25 grams per teaspoon. 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.
Put next to water — 1 g per mL exactly — dry breadcrumbs measures 0.45649 g per mL. That ratio, 45.65%, is what separates this page from every other ingredient in the same units, and it is measured rather than defined.
A level teaspoon of dry breadcrumbs weighs 2.25 g. A kitchen scale that reads to the nearest gram is therefore working at roughly 44.4% resolution on a single spoonful, which is why measuring spoons beat scales below about 5 g and lose to them above it. Three teaspoons make a tablespoon, so the same spoonful is 6.75 g if the recipe scales up.
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.
The condition this weight assumes: Fine, dry and unseasoned. Fresh breadcrumbs weigh about half as much per cup because the crumb has not collapsed.
The formula
teaspoons- The amount of dry breadcrumbs you are converting, in teaspoons
2.25- Grams per teaspoon 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 teaspoons.
- It is multiplied by 2.25, the grams-per-teaspoon 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
3/4 tsp of dry breadcrumbs in grams
A recipe calling for 3/4 tsp of dry breadcrumbs needs 1.6875 grams on the scale. The arithmetic is 0.75 × 2.25 = 1.6875, and halving the recipe halves the weight to 0.84375 grams.
1 1/2 tsp of dry breadcrumbs in grams
Take 1 1/2 tsp of dry breadcrumbs: 1.5 × 2.25 gives 3.375 grams. Doubling the batch takes it to 6.75 grams, because the relationship is a straight proportion once the density is known.
4 tsp of dry breadcrumbs in grams
4 tsp of dry breadcrumbs weighs out at 9 grams. Divide 9 by 2.25 and you get back to 4 tsp, which is the quickest check that the factor is the right way up.

Frequently asked questions
How many grams are in 1 tsp of dry breadcrumbs?
One teaspoon of dry breadcrumbs is 2.25 grams. Half that quantity is 1.125 grams and double it is 4.5 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 teaspoon of dry breadcrumbs is 2.25 g, and a scale reading to the nearest gram is working at 44.4% 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 teaspoons of dry breadcrumbs is 500 g?
500 g of dry breadcrumbs is 222.22 teaspoons — 0.444444 teaspoons to one gram, so 500 × 0.444444 = 222.22. Going that way is a division by 2.25, or a multiplication by 0.444444 if you prefer.
