40 Grams of Cocoa Powder to Cups
½ cup in a US cup — and what that looks like with a measuring spoon
40 grams of unsweetened cocoa powder is ½ cup in a US cup. In the kitchen that is ¼ cup, 3 tablespoons plus 1½ teaspoons.
Grams weigh and cups fill, so the answer only exists once you say what is in the cup. A US cup of unsweetened cocoa powder weighs 85 g, and every figure on this page comes from that one number.
It also depends on whose cup you mean, though not much at this weight. A 250 ml metric cup — the standard in the UK, Australia, New Zealand and Canada — holds about 5.7% more than the 236.6 ml US cup, but 40 g of unsweetened cocoa powder still rounds to ½ cup in both: 0.47 US cups against 0.45 metric.
Round to the nearest measure in a standard cup set — ½ cup — and you are 3 g over, about 8% of the amount.
40 g of cocoa powder in each cup standard
| Cup standard | Size | Grams per cup | Cups |
|---|---|---|---|
| US customary | 236.6 ml | 85 g | ½ |
| Metric (UK, AU, NZ, CA) | 250 ml | 90 g | ½ |
| Imperial (older UK) | 284 ml | 102 g | ⅜ |
A recipe that says "cups" without saying which one is almost always American. At 40 g it barely matters for unsweetened cocoa powder — both cups round to the same measure — but on a larger batch the 5.7% gap compounds.
How to measure 40 g of cocoa powder without scales
Cocoa powder is very light and clumps in the tin. Spoon it into the cup and level it rather than scooping, and sift it if the recipe asks.
Unsweetened cocoa powder is 85 g per cup. Natural and Dutch-process cocoa weigh close enough to use the same figure, though they behave differently with baking soda.
- Build it as ¼ cup, 3 tablespoons plus 1½ teaspoons rather than guessing at ½ of a cup.
- 40 g is 7.53 tablespoons of unsweetened cocoa powder, at 5.31 g per tablespoon.
- A digital scale removes the question entirely, and costs less than the ingredients it saves.

Frequently asked questions
How many cups is 40 grams of cocoa powder?
40 grams of unsweetened cocoa powder is ½ cup in a US cup, based on 85 g per cup. A 250 ml metric cup rounds to the same ½ cup.
What is the easiest way to measure 40 g of cocoa powder?
¼ cup, 3 tablespoons plus 1½ teaspoons — built from a standard cup and spoon set. Cocoa powder is very light and clumps in the tin. Spoon it into the cup and level it rather than scooping, and sift it if the recipe asks.
Is 40 g of cocoa powder the same in cups in the UK?
Near enough. A UK, Australian, New Zealand or Canadian metric cup is 250 ml against the US cup's 236.6 ml, so the exact answers differ — 0.47 US cups against 0.45 metric — but both round to ½ cup, and at this weight you can use either.
Can I just use ½ cup instead?
½ cup of unsweetened cocoa powder weighs about 43 g, so you would be 3 g over. For a sauce or a soup that is fine; for a cake, where the flour-to-liquid ratio sets the crumb, weigh it.
How many ounces is 40 grams?
40 grams is 1.41 ounces by weight. Unlike cups, that answer is the same whatever you are measuring — ounces weigh, fluid ounces fill, and they are not the same unit.
