Question: why 16 ounces in a pound?
Answer: One should remember that the weights on the scales were marked in oz, of 1, 2, 4, 8, &c, and in one case, the 16 oz simply became the pound. The stone of 14 lb, being of 98000 grains, troy, comes from the wool trade, where the main customers rated it as 20 lbs of 4900 grains troy.
