The bananas you can buy in the West are all clones of each other. Their mass distribution is tight enough that it wouldn't make much of a difference given that the numbers in the article are only very approximate to begin with.

In any case, my point in the comment was that the unit is arbitrary, they are only talking about ratios. So any unit (or no unit at all) would do.

So then, how about a ratio of spoons to no-spoons?

Sorry to pun, I couldn't resist.
