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.
