One millilitre of dry breadcrumbs is 0.45648931 grams, so converting millilitres of dry breadcrumbs to grams means multiplying by 0.45648931. That factor is specific to this ingredient — it comes from its density, not from any relationship between the two units.
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.
Dry breadcrumbs has a density of 0.45649 g per mL, so 100 mL of it weighs 45.65 g and 250 mL weighs 114.1 g. That single figure is what every other number on this page is built from — water is 1.00 g per mL, so this ingredient is 45.65% as heavy as the same volume of water.
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
millilitres- The amount of dry breadcrumbs you are converting, in millilitres
0.456489306475- Grams per millilitre 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 millilitres.
- It is multiplied by 0.456489306475, the grams-per-millilitre 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
15 mL of dry breadcrumbs in grams
A recipe calling for 15 mL of dry breadcrumbs needs 6.84734 grams on the scale. The arithmetic is 15 × 0.45648931 = 6.8473396, and halving the recipe halves the weight to 3.42367 grams.
100 mL of dry breadcrumbs in grams
100 mL of dry breadcrumbs weighs out at 45.6489 grams. Divide 45.6489 by 0.45648931 and you get back to 100 mL, which is the quickest check that the factor is the right way up.
250 mL of dry breadcrumbs in grams
A recipe calling for 250 mL of dry breadcrumbs needs 114.122 grams on the scale. The arithmetic is 250 × 0.45648931 = 114.12233, and halving the recipe halves the weight to 57.0612 grams.

Frequently asked questions
How many grams are in 1 mL of dry breadcrumbs?
One millilitre of dry breadcrumbs is 0.45648931 grams. Half that quantity is 0.228245 grams and double it is 0.912979 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 millilitre of dry breadcrumbs is 0.4565 g, and a scale reading to the nearest gram is working at 219% 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 millilitres of dry breadcrumbs is 500 g?
500 g of dry breadcrumbs is 1095.3 millilitres — 2.19063 millilitres to one gram, so 500 × 2.19063 = 1095.3. Going that way is a division by 0.456489, or a multiplication by 2.19063 if you prefer.
