How Much is a Stone in Pounds?

How much is a stone in pounds? This is a practice used in England to weigh people or at least it use to be. I think it is something that is not done as often now but 8 stones is equivalent to 100 pounds. Now I don’t know how big the stones they use in England but wow, how accurate would that be? So 1 stone would weigh 12.5 pounds. You can find more information here:
