Here is the number first, as it should be: 2 cups of powdered milk weighs approximately 240 g. One cup is 120 g (spooned and levelled, USDA), so the maths is 120 × 2. Nonfat dry milk powder; reconstitutes with water. It shows up across baking, bread machines, hot chocolate and camping food, and because it is one of those ingredients where a heavy hand with the scoop quietly changes the recipe, weighing is worth the thirty seconds it takes. This page is built to be used at the counter: the table first, then examples, then the method and the mistakes, then answers to the questions people actually ask about this conversion.
Full conversion table
This table is the working heart of the page. One cup of powdered milk weighs 120 g (spooned and levelled, USDA), and each row multiplies that by the cup amount. Figures are rounded to the nearest gram and are approximate: use them as weighing targets, and let the scale have the last word when the bake matters.
| Cups | Grams (approx.) |
|---|---|
| 1/4 cup | 30 g |
| 1/3 cup | 40 g |
| 1/2 cup | 60 g |
| 2/3 cup | 80 g |
| 3/4 cup | 90 g |
| 1 cup | 120 g |
| 1 1/4 cups | 150 g |
| 1 1/2 cups | 180 g |
| 1 3/4 cups | 210 g |
| 2 cups | 240 g |
| 2 1/2 cups | 300 g |
| 3 cups | 360 g |
The table rounds to whole grams, and that rounding is honest: a kitchen scale that reads to the gram cannot meaningfully distinguish 240 g from 241 g in a recipe that also depends on oven temperature, humidity and the age of the ingredients. Do not chase the last gram. What matters is being in the right neighbourhood — 240 g rather than a scooped cup that quietly weighed 270 g — and the table puts you there every time.
How 240 g works in practice
Example 1 — doubling for guests
A recipe calling for 1 cup (120 g) of powdered milk doubles to 2 cups (240 g). Weigh it, double the rest, and use a bigger tin. That is the whole technique, and it is worth doing properly because a doubled recipe that is also a guessed recipe is two sources of error at once. Weighing removes one of them completely.
Example 2 — the two-cup recipe
When the recipe itself asks for 2 cups, weigh 240 g into a tared bowl, spooned and levelled. Recipes built around this quantity are usually batch recipes (baking, bread machines, hot chocolate and camping food), and batch recipes punish inaccuracy more than small ones do: an error that would be a rounding difference in a single cake becomes a visible difference across a tray. Weigh, and the batch comes out the same every time.
Example 3 — scaling by weight, not by eye
Suppose you want one and a half times the recipe instead of double. One and a half cups is 180 g, and the multiplier for every other ingredient is 1.5. Try doing that with cup measures — a cup and a half of powdered milk scooped by eye — and you will see why weight wins: the scale does the fractions for you, and every ingredient scales by the same clean factor.
Source, method and the honest caveats
Two facts sit behind every number here. First, the source: USDA, which lists one cup of powdered milk at 120 g. Second, the method: spooned and levelled. Together they define the cup this page is talking about. Change either one and the numbers shift — which is exactly what happens when a recipe from another source quotes a different weight for the same ingredient. It is usually measuring a different cup. There is no famous dispute about the weight of powdered milk: the figure used here is stable across the sources we checked, which is one reason this conversion is reliable. Even so, every figure on this page is labelled approximate, because how full the cup is, how settled the ingredient is, and the temperature in your kitchen all move the number a little. When precision matters, verify with a kitchen scale.
Making the conversion work in a real kitchen
A real kitchen is not a laboratory, so here is the practical version. Weigh powdered milk when the recipe is a bake or a batch you want to repeat; measure by cup when it is a soup, a sauce or a weekday dish where a few grams either way will not show. Keep your measuring cups honest — a dented cup or a mismatched set is a quiet source of error — and keep the ingredient itself in good shape: Airtight container, cool and dry, up to 1 year. Fresh, dry and properly stored, powdered milk weighs what the table says it weighs.
Bigger batches, smaller batches
Batch size is a choice, and weight is what makes the choice easy. From 2 cups (240 g), a half batch is 1 cup (120 g), a quarter batch is 1/2 cup (60 g), one and a half times is 3 cups (360 g), and a triple batch is 6 cups (720 g). The multiplication never changes — cups × 120 g — so the only new thinking is practical. Large batches need large bowls, large tins and longer bakes, and the baking time grows by roughly a quarter rather than tripling, so test with a skewer and watch the colour. Small batches need small tins and shorter bakes, and they are the ones that catch people out, because a small cake in a hot oven goes from done to dry in minutes. Scale the salt and raising agents with everything else, weigh every scaled amount instead of estimating it, and write the scaled figures on the recipe before you start. A recipe that is scaled on paper and weighed on a scale is a recipe you can make at any size, any number of times, with the same result.
Frequently asked questions
How many grams is 2 cups of powdered milk?
2 cups of powdered milk weighs approximately 240 g. One cup is 120 g (spooned and levelled, USDA), so the calculation is 120 × 2 = 240 g. The figure is approximate: how you fill the cup moves the weight, so verify with a kitchen scale when precision matters.
How many tablespoons are in 2 cups of powdered milk?
There are 32 tablespoons in 2 cups, and one tablespoon of powdered milk weighs about 7.5 g (120 g per cup ÷ 16). Spoonfuls are useful for small adjustments, but for the full two cups, weighing the 240 g directly is more accurate than counting 32 spoonfuls.
Can I measure 2 cups of powdered milk without a scale?
Yes — use a dry measuring cup, spoon the powdered milk in loosely, and level it off with the back of a knife. Do not scoop with the cup itself and do not pack it unless the method says packed. Two careful cups will land close to 240 g, which is good enough for everyday cooking, though a scale is better for baking.
Why do different websites give different weights for powdered milk?
Because they measure the cup differently. USDA lists 120 g per cup spooned and levelled, while other sources may scoop, sift or pack, and each method gives a different weight. The ingredient itself has not changed — only the measuring method has. Match the method and the numbers agree.
Does 2 cups of powdered milk weigh the same as 2 cups of water?
No. Two cups of water weighs about 474 g, while 2 cups of powdered milk weighs 240 g. A cup measures volume, not weight, so every ingredient has its own grams per cup — which is why a single universal cups-to-grams number cannot exist and why each ingredient needs its own conversion.
What if my recipe calls for 2 cups but I only have a partial bag?
Weigh what you have. If the bag holds 180 g, that is 1 1/2 cups, and you can scale the whole recipe down by a quarter — multiply every other ingredient by 0.75. Weighing makes that rescue possible; guessing by eye does not.
