40 Grams of Coconut Flour in Cups
40 grams of coconut flour doesn't land on a clean fraction, so the result below is calculated exactly rather than rounded to a common measure. Based on a density of 112g per cup, it equals 0.36 cups.

40 grams of coconut flour = 0.36 cups (⅜ cup / 5.7 tbsp / 17.1 tsp)
Coconut Flour has a density of approximately 112g per cup. Very dense and absorbent — measure carefully. Source: USDA FoodData Central. This is the figure used everywhere on this page, including the tablespoon and teaspoon values, so the numbers stay consistent whether you're reading the summary line, the table, or the FAQ answers below.
| Grams | Cups | Fraction | Tablespoons | Teaspoons |
|---|---|---|---|---|
| 30g | 0.27 | ¼ | 4.3 | 12.9 |
| 35g | 0.31 | ⅓ | 5.0 | 15.0 |
| 40g | 0.36 | ⅜ | 5.7 | 17.1 |
| 45g | 0.40 | ⅜ | 6.4 | 19.3 |
| 50g | 0.45 | ½ | 7.1 | 21.4 |
How 40g Converts, Step by Step
40g divided by 112g (the weight of one cup of coconut flour) equals 0.36 cups. Multiplying that by 16 gives 5.7 tablespoons, and by 48 gives 17.1 teaspoons, since one cup always equals 16 tablespoons or 48 teaspoons regardless of the ingredient.
Coconut Flour is lighter than water, which weighs about 236g per cup. That's why 40g of coconut flour takes up more volume (84ml) than the same weight of water would (40ml). For a side-by-side look at how other ingredients compare, see the 40 grams to cups page.
If You're Using a Metric or Imperial Cup
The 0.36 cup figure above uses the US Customary cup (236.588ml). Recipes written outside the US sometimes use a metric cup (250ml) or an imperial (uk) cup (284.131ml) instead. At 40g, that's ⅓ metric cups or ⅓ imperial cups of coconut flour, close to the US figure but not identical. The cup standard switch in the converter above recalculates this instantly for any gram amount.
Scaling This 40g Amount
Doubling a recipe that calls for 40g of coconut flour means weighing 80g, or measuring 0.71 cups if you're working by volume instead of weight. Halving it means 20g, or 0.18 cups. Weight scales exactly with simple multiplication; cup measurements compound any scooping error each time they're doubled or halved, so weighing is more reliable the more a recipe is scaled.
Coconut Flour Next to Other Flours
Within flours, density still varies by ingredient. At 40g, all-purpose flour (125g per cup) measures ⅓ cup, while bread flour (127g per cup) measures ⅓ cup, compared to ⅜ cup for coconut flour. Swapping ingredients in a recipe by cup measurement alone, without adjusting for this difference, changes the actual weight used.
Where This Amount Shows Up in Recipes
- Coconut flour recipes typically use much less than wheat flour — often just 60g to 90g per batch.
- Coconut flour pancakes usually call for 30g to 40g for four servings.
- Low-carb muffins often need about 60g total.
Measuring This Precisely
Flours
Spoon the flour into the cup, then level it off with a straight edge. Never scoop directly from the bag — that packs it down and adds extra weight.
For exact results
Sifting before measuring lowers the weight per cup by adding air, so a recipe written for sifted flour will call for a slightly larger volume than one written for unsifted. Check whether your recipe specifies sifted flour before comparing it to a standard chart.

Frequently Asked Questions
What is 40 grams of coconut flour in cups exactly?+
40 grams of coconut flour equals 0.36 cups, based on a density of 112g per cup.
Why doesn't 40g of coconut flour match a simple fraction?+
40g isn't a multiple of coconut flour's per-cup weight, so the cup value lands between common fractions. The closest practical measure is ⅜ cup.
What's the most reliable way to measure 40g of coconut flour?+
A kitchen scale set to grams gives an exact 40g reading. Cups only approximate this amount, since ⅜ cup rounds to the nearest practical fraction.
Is 40g likely a typo for a rounder amount?+
Possibly, if a recipe seems to expect a cleaner number. Check the nearby amounts table below for the closest common gram values for coconut flour.
