To convert teaspoons of panko breadcrumbs into grams, multiply by 1.25: one teaspoon comes to 1.25 grams. Every ingredient has its own figure here, because the units are measuring different things and only the density links them.
The density behind that figure is 0.25361 g per mL, against 1.00 for water. A cup of water weighs 236.6 g and a cup of panko breadcrumbs weighs 60 g, so this ingredient is 25.36% as heavy as the same volume of water — the single fact the whole page rests on.
A level teaspoon of panko breadcrumbs weighs 1.25 g. A kitchen scale that reads to the nearest gram is therefore working at roughly 80% 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 3.75 g if the recipe scales up.
Grams are the unit this conversion is really for. A domestic scale resolves to a gram, which is 1.67% of a cup of panko breadcrumbs, so weighing gets an accuracy no measuring cup can reach. A 500 g pack of it is 8.333 cups, and a 1 kg pack 16.67.
What the number depends on: The lightest crumb there is. The flakes are large and mostly air, which is exactly what keeps a coating crisp.
The formula
teaspoons- The amount of panko breadcrumbs you are converting, in teaspoons
1.25- Grams per teaspoon for panko breadcrumbs, from its density of 0.25361 g/mL
grams- The equivalent quantity in grams
How it works, step by step
- Enter the quantity in teaspoons.
- It is multiplied by 1.25, the grams-per-teaspoon figure for panko 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 panko breadcrumbs in grams
A recipe calling for 3/4 tsp of panko breadcrumbs needs 0.9375 grams on the scale. The arithmetic is 0.75 × 1.25 = 0.9375, and halving the recipe halves the weight to 0.46875 grams.
1 1/2 tsp of panko breadcrumbs in grams
1 1/2 tsp of panko breadcrumbs weighs out at 1.875 grams. Divide 1.875 by 1.25 and you get back to 1 1/2 tsp, which is the quickest check that the factor is the right way up.
4 tsp of panko breadcrumbs in grams
Take 4 tsp of panko breadcrumbs: 4 × 1.25 gives 5 grams. Doubling the batch takes it to 10 grams, because the relationship is a straight proportion once the density is known.
How to read your score
Frequently asked questions
How many grams are in 1 tsp of panko breadcrumbs?
One teaspoon of panko breadcrumbs is 1.25 grams. Half that quantity is 0.625 grams and double it is 2.5 grams, so the figure scales straight up and down — there is no offset in this conversion, only the factor.
Why is a cup of panko breadcrumbs not 236 g like water?
Because weight per cup depends on what is in the cup. Panko breadcrumbs has a density of 0.25361 g per mL where water has 1.00, so a cup of it weighs 60 g rather than 236.6 g. That is a difference of 176.6 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 panko breadcrumbs by roughly 20% — about 6 g either side of 60 g — because the lightest crumb there is. Weighing removes the question entirely.
Is a fluid ounce of panko 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 panko breadcrumbs weighs 0.2646 oz, so the two readings differ by 73.5%. 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 panko breadcrumbs would weigh 63.401 g instead of 60 g — 3.4 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 panko breadcrumbs is 1.25 g, and a scale reading to the nearest gram is working at 80% 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 panko breadcrumbs is 500 g?
500 g of panko breadcrumbs is 400 teaspoons — 0.8 teaspoons to one gram, so 500 × 0.8 = 400. Going that way is a division by 1.25, or a multiplication by 0.8 if you prefer.
