100 grams of black beans = 0.58 cups (⅝ cup / 9.3 tbsp / 27.9 tsp)
Black Beans has a density of approximately 172g per cup. Canned and drained. Rinsing versus straight-draining can shift this by 5-10g. 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 |
|---|---|---|---|---|
| 90g | 0.52 | ½ | 8.4 | 25.1 |
| 95g | 0.55 | ½ | 8.8 | 26.5 |
| 100g | 0.58 | ⅝ | 9.3 | 27.9 |
| 110g | 0.64 | ⅝ | 10.2 | 30.7 |
| 120g | 0.70 | ⅔ | 11.2 | 33.5 |
How the 100g Figure Is Calculated
100g divided by 172g (the weight of one cup of black beans) equals 0.58 cups. Multiplying that by 16 gives 9.3 tablespoons, and by 48 gives 27.9 teaspoons, since one cup always equals 16 tablespoons or 48 teaspoons regardless of the ingredient.
Black Beans is lighter than water, which weighs about 236g per cup. That's why 100g of black beans takes up more volume (138ml) than the same weight of water would (100ml). For a side-by-side look at how other ingredients compare, see the 100 grams to cups page.
If Your Recipe Uses Metric or Imperial Cups
The 0.58 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 100g, that's ½ metric cups or ½ imperial cups of black beans, close to the US figure but not identical. The cup standard switch in the converter above recalculates this instantly for any gram amount.
Scaling 100g Up or Down
Doubling a recipe that calls for 100g of black beans means weighing 200g, or measuring 1.16 cups if you're working by volume instead of weight. Halving it means 50g, or 0.29 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.
Black Beans vs. Other Beans & Legumes
Within beans & legumes, density still varies by ingredient. At 100g, chickpeas (152g per cup) measures ⅔ cup, compared to ⅝ cup for black beans. Swapping ingredients in a recipe by cup measurement alone, without adjusting for this difference, changes the actual weight used.
Using Black Beans in Recipes
- Recipes typically call for this ingredient in amounts ranging from a tablespoon to a full cup, depending on the dish.
- Check your specific recipe for the exact gram amount, then use the converter above to find the matching cup measurement.
How to Measure It Accurately
Beans & Legumes
Pour into the cup loosely and level the top. Dried beans and lentils don't compress the way flour does.
For exact results
Dried beans roughly double or triple in volume once soaked and cooked, so a recipe calling for a cup of cooked beans needs considerably less than a cup of the dried form.

Frequently Asked Questions
What is 100 grams of black beans in cups?+
100 grams of black beans is 0.58 cups (⅝ cup), or 9.3 tablespoons.
How do I measure 100 grams of black beans without a scale?+
Use ⅝ cup, spooned in and leveled off with a straight edge. If you only have tablespoons, use 9.3 tablespoons instead.
Why is black beans's gram-to-cup ratio different from other ingredients?+
Black Beans weighs 172g per cup because of its own density. Canned and drained. Rinsing versus straight-draining can shift this by 5-10g.
Does a metric or imperial cup change this 100g conversion?+
Yes, slightly. 100g of black beans is ½ metric cups or ½ imperial cups, versus ⅝ US cups, since each cup standard holds a different volume.
