~ Fun Fact ~
Down through the centuries, a stone meant different things to different people. One of the strangest uses of this measurement involved weighing livestock and meat products in England. When a live animal was weighed, a stone represented 14 pounds. But when the cow, sheep, or other animal was slaughtered, its carcass or meat was weighed in a stone that represented 8 pounds! This practice continued until the mid-1900s.
