The Amsterdam pound versus the English pound (weights)

I usually do not think about this issue, but I have known that the Amsterdam pound is heavier than the English pound. The Amsterdam pound is about 494.1 grams while the English pound is 453.6 grams. That is a ratio of 1.0892857 to 1.0. That means that an English 42 pound shot is 38.56 Amsterdam pounds. The Dutch 6 pound shot is roughly 6.5 English pounds. The Dutch 8 pound shot is 8.7 English pounds (you can see my American-centric viewpoint, since I use the period as the decimal point, not the comma).
