Powdered Milk: Cups to Grams
One US cup (240 ml) of powdered milk weighs 128 grams; half a cup weighs 64 grams. A quarter cup is 32 grams, a tablespoon is 8 grams and a teaspoon is 2.67 grams. A cup measures volume, not weight, so these numbers are for powdered milk only: a cup of honey weighs 340 grams.

Ounces here are ounces of weight (1 oz = 28.35 g), not fluid ounces. One US cup is 8 fluid ounces of volume whatever is in it, but what it weighs in ounces depends on the ingredient: a cup of powdered milk weighs about 4.52 oz. Why these two are not the same. Decimals for thirds are rounded (1/3 cup is 0.333 cups), and each linked amount opens a page comparing every ingredient at that measure.

About measuring powdered milk
Powdered milk, or dried milk, is a fine light powder used to enrich breads and add body to sauces, and one US cup weighs about 128 grams. Like other powders it clumps and holds air, so scooped cups vary. It is potent for its weight, adding milk solids without liquid, so bakers often measure it in tablespoons. When a recipe leans on powdered milk for a soft, tender crumb, weighing keeps the enrichment consistent.
Powdered milk clumps like flour. Sift or weigh it so your enriched dough stays consistent.
How many grams is a cup of powdered milk?
One US cup (240 ml) of powdered milk weighs about 128 grams. Because a cup measures volume rather than weight, that figure is specific to powdered milk and does not transfer to any other ingredient: the same cup holds 125 grams of all-purpose flour and 340 grams of honey.
- 1/4 cup of powdered milk is about 32 grams
- 1/3 cup of powdered milk is about 43 grams
- 1/2 cup of powdered milk is about 64 grams
- 2/3 cup of powdered milk is about 85 grams
- 3/4 cup of powdered milk is about 96 grams
- 1 1/2 cups of powdered milk is about 192 grams
- 2 cups of powdered milk is about 256 grams
- 3 cups of powdered milk is about 384 grams
Working the other way round, 100 grams of powdered milk is about 0.781 cups, and 500 grams is about 3.91 cups.
Does it matter which cup my recipe means?
It does, though less than the ingredient itself. This page uses the US legal cup of 240 ml. An Australian metric cup is 250 ml, so a metric cup of powdered milk comes to about 133 grams, and the old British imperial cup of 284.1 ml holds about 152 grams. See cup sizes by country for every standard side by side.
Frequently asked questions
How many grams is 1 cup of powdered milk?
One US cup of powdered milk is about 128 grams. It is a fine, light powder that holds air, so it clumps easily.
How many grams is a tablespoon of powdered milk?
About 8 grams. A cup is around 128 grams and holds 16 tablespoons, so each tablespoon is roughly 8 grams.
Why add powdered milk to bread?
It adds milk solids for a softer, richer crumb and better browning without extra liquid. Weighing keeps that enrichment consistent from loaf to loaf.
Where this figure comes from
We have not yet found a published reference that states a weight for a cup of powdered milk. The 128 grams on this page follows the calibration the rest of the site is built on, with butter at 227 grams per cup, water at 240, all-purpose flour at 125 and granulated sugar at 200. Treat it as a good working figure rather than a cited one. If you have a better source, tell us and we will check it and credit you.
Published figures for the same ingredient vary between references anyway, because how an ingredient is packed changes what a cup of it weighs. Treat any cup figure as accurate to within a few percent, and weigh on a scale when a recipe is sensitive. Our full approach is on the methodology page.
