|---|---|---|---|---|
| 30g | 0.13 | ⅛ | 2.0 | 6.0 |
| 35g | 0.15 | ⅛ | 2.3 | 7.0 |
| 40g | 0.17 | ⅛ | 2.7 | 8.0 |

How 40g Converts, Step by Step
40g divided by 240g (the weight of one cup of tahini) equals 0.17 cups. Multiplying that by 16 gives 2.7 tablespoons, and by 48 gives 8.0 teaspoons, since one cup always equals 16 tablespoons or 48 teaspoons regardless of the ingredient.
Tahini is denser than water, which weighs about 236g per cup. That's why 40g of tahini fills less volume (39ml) 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 0.17 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 ⅛ metric cups or ⅛ imperial cups of tahini, 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 tahini means weighing 80g, or measuring 0.33 cups if you're working by volume instead of weight. Halving it means 20g, or 0.08 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.
Tahini Next to Other Condiments & Sauces
Within condiments & sauces, density still varies by ingredient. At 40g, almond butter (240g per cup) measures ⅛ cup, while peanut butter (258g per cup) measures ⅛ cup, compared to ⅛ cup for tahini. 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
- Hummus recipes typically use 60g to 90g of tahini per batch.
- Tahini dressings often call for 30g mixed with lemon and garlic.
- Halva and tahini cookies usually need about 120g.
Measuring This Precisely
Condiments & Sauces
Use a spatula to level thick condiments like peanut butter or tahini after pressing them into the cup to remove air gaps.
For exact results
Stir thick condiments well before measuring, since separation during storage (common in natural nut butters) can make the top and bottom of the jar measure differently.

Frequently Asked Questions
What is 40 grams of tahini in cups exactly?+
40 grams of tahini equals 0.17 cups, based on a density of 240g per cup.
Why doesn't 40g of tahini match a simple fraction?+
40g isn't a multiple of tahini's per-cup weight, so the cup value lands between common fractions. The closest practical measure is ⅛ cup.
What's the most reliable way to measure 40g of tahini?+
A kitchen scale set to grams gives an exact 40g reading. Cups only approximate this amount, since ⅛ 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 tahini.
