One gram of dry breadcrumbs is 0.44444444 teaspoons, so converting grams of dry breadcrumbs to teaspoons means multiplying by 0.44444444. That factor is specific to this ingredient — it comes from its density, not from any relationship between the two units.
Water is the yardstick: 1 mL of it weighs 1 g. Dry breadcrumbs comes in at 0.45649 g per mL, or 45.65% of water, which is why a cup of it is 108 g rather than 236.6 g. Volume and weight only line up for water, and only in metric.
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.
How the figure is arrived at: Fine, dry and unseasoned. Fresh breadcrumbs weigh about half as much per cup because the crumb has not collapsed.
The formula
grams- The amount of dry breadcrumbs you are converting, in grams
0.444444444444- Teaspoons per gram for dry breadcrumbs, from its density of 0.45649 g/mL
teaspoons- The equivalent quantity in teaspoons
How it works, step by step
- Enter the quantity in grams.
- It is multiplied by 0.444444444444, the teaspoons-per-gram figure for dry breadcrumbs.
- The result appears in teaspoons, with a second reading in mL 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 dry breadcrumbs in teaspoons
A recipe calling for 50 g of dry breadcrumbs needs 22.2222 teaspoons on the scale. The arithmetic is 50 × 0.44444444 = 22.222222, and halving the recipe halves the weight to 11.1111 teaspoons.
150 g of dry breadcrumbs in teaspoons
A recipe calling for 150 g of dry breadcrumbs needs 66.6667 teaspoons on the scale. The arithmetic is 150 × 0.44444444 = 66.666667, and halving the recipe halves the weight to 33.3333 teaspoons.
500 g of dry breadcrumbs in teaspoons
Take 500 g of dry breadcrumbs: 500 × 0.44444444 gives 222.222 teaspoons. Doubling the batch takes it to 444.444 teaspoons, because the relationship is a straight proportion once the density is known.

Frequently asked questions
How many teaspoons are in 1 g of dry breadcrumbs?
One gram of dry breadcrumbs is 0.44444444 teaspoons. Half that quantity is 0.222222 teaspoons and double it is 0.888889 teaspoons, 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 much does 2 tsp of dry breadcrumbs weigh?
2 tsp of dry breadcrumbs comes to 4.5 g, or 4.5 grams. This page runs that calculation in reverse — enter a weight and it returns the volume — and the teaspoons-to-grams page does it in the direction the question is usually asked.
