290 grams of mashed banana = 1.29 cups (1¼ cup / 20.6 tbsp / 61.9 tsp)
Mashed Banana has a density of approximately 225g per cup. Ripeness affects density slightly, but this figure stays stable across ripe bananas. 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 |
|---|---|---|---|---|
| 275g | 1.22 | 1¼ | 19.6 | 58.7 |
| 280g | 1.24 | 1¼ | 19.9 | 59.7 |
| 290g | 1.29 | 1¼ | 20.6 | 61.9 |
| 300g | 1.33 | 1⅓ | 21.3 | 64.0 |
| 325g | 1.44 | 1½ | 23.1 | 69.3 |
How 290g Converts, Step by Step
290g divided by 225g (the weight of one cup of mashed banana) equals 1.29 cups. Multiplying that by 16 gives 20.6 tablespoons, and by 48 gives 61.9 teaspoons, since one cup always equals 16 tablespoons or 48 teaspoons regardless of the ingredient.
Mashed Banana is lighter than water, which weighs about 236g per cup. That's why 290g of mashed banana takes up more volume (305ml) than the same weight of water would (291ml). For a side-by-side look at how other ingredients compare, see the 290 grams to cups page.
If You're Using a Metric or Imperial Cup
The 1.29 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 290g, that's 1¼ metric cups or 1⅛ imperial cups of mashed banana, 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 290g Amount
Doubling a recipe that calls for 290g of mashed banana means weighing 580g, or measuring 2.58 cups if you're working by volume instead of weight. Halving it means 145g, or 0.64 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.
Mashed Banana Next to Other Produce & Purees
Within produce & purees, density still varies by ingredient. At 290g, applesauce (244g per cup) measures 1¼ cup, while pumpkin puree (245g per cup) measures 1⅛ cup, compared to 1¼ cup for mashed banana. Swapping ingredients in a recipe by cup measurement alone, without adjusting for this difference, changes the actual weight used.
Using Mashed Banana 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.
Measuring This Precisely
Produce & Purees
Purees should be leveled with a spatula. Chopped produce should be packed only if the recipe specifically calls for it.
For exact results
Puree consistency varies by brand and preparation method, so a homemade puree may measure differently by weight than a canned one even at the same cup volume.

Frequently Asked Questions
What is 290 grams of mashed banana in cups exactly?+
290 grams of mashed banana equals 1.29 cups, based on a density of 225g per cup.
Why doesn't 290g of mashed banana match a simple fraction?+
290g isn't a multiple of mashed banana's per-cup weight, so the cup value lands between common fractions. The closest practical measure is 1¼ cup.
What's the most reliable way to measure 290g of mashed banana?+
A kitchen scale set to grams gives an exact 290g reading. Cups only approximate this amount, since 1¼ cup rounds to the nearest practical fraction.
Is 290g 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 mashed banana.
