Which average weight % of the banana is edible? i.e. Which % of the banana is not peel?

I had an application not long ago for which I needed the answer to the question as written.

America's Test Kitchen (sorry, paywalled) has a recipe for banana bread that I love. I save over-ripe banana chunks in the freezer until I feel like making banana bread. The recipe calls for "6 large very ripe bananas (about 2 1/4 pounds), peeled". My bananas were already peeled and chunked. I wanted to follow the recipe very precisely because the recipe and particular methods were new to me.

So how much peeled banana equals 2.25 pounds of unpeeled banana?

My doctor has been nagging me to eat breakfast, so most days I manage to eat a banana early in my day. For one week I weighed the banana unpeeled and peeled. Then I struck an average.

My average banana weighed 183 grams unpeeled, 116 grams peeled. 185/116=1.58.

So, 2.25 pounds (1021 grams) of unpeeled banana = 1.43 pounds (647 grams) of peeled banana.

My average banana (very average in the store, Dole brand) was 62.4% edible.

Per the National Nutrient Database for Standard Reference Release 28, the "refuse" content of a banana is 36%, attributed to the peeling.

Just tested one (I'm sure it would be close enough to average for my purposes) to see if it was more equitable to purchase a bulk box of frozen organic banana chunks.

Peel = 93g, fruit = 125g = 57% edible.

1. I don't know any caloric measurements for bananas that include the peel. They assume you're discarding it.

2. Since you don't have a scale, you can also get the approximate calories by looking at the length of a banana.

+-------------+---------------------------+---------------+-----------+
| Banana Size |          Length           |    Weight     | Calories  |
+-------------+---------------------------+---------------+-----------+
| Extra Small | Under 6 inches (15 cm)    | 2.9 oz (81g)  |        72 |
| Small       | 6 – 7 inches (15 – 18 cm) | 3.6 oz (101g) |        90 |
| Medium      | 7 – 8 inches (18 – 20 cm) | 4.2 oz (118g) |       105 |
| Large       | 8 – 9 inches (20 – 23 cm) | 4.8 oz (136g) |       121 |
| Extra Large | Over 9 inches (23 cm)     | 5.4 oz (152g) |       135 |

• Bananas vary: sizes and corresponding weights are approximate.
• Calories based on the weight shown in grams.

3. There are many different varieties of bananas, they vary in length, and even change weight as they ripen. So using an "average weight" to count your calories isn't very accurate. As you can see from the approximate calories above, this can be a significant caloric difference, and if used in a recipe could greatly affect the outcome.
