Pasted from another site:

The 16 gauge gets its number because its bore is the same diameter as a round ball weighing 1/16th of a pound: 1 ounce. A classic theory of shotshell efficiency suggests any shotgun patterns best with a shotload equal in weight to a bore-size lead ball. In shotgunning lore this is known as a "square" load.
A square load is one where the height of the shot column is equal to the width of the shot column. Somewhere on the internet I have seen a graph/chart of square loads by gauge. If I recall correctly a 12ga was closest with 1 1/16 ounce and 10 gauge with a little more than 1 1/4 ounce and the 16ga was 15/16 of an ounce. I'll try to find it.
