What is a stone?
Fourteen pounds. Still the everyday unit of body weight in Britain and Ireland, and nowhere else.
What is a slug?
The mass that one pound-force accelerates at one foot per second squared — 32.174 pounds. It exists so that F = ma works in US customary units without a conversion constant, and it is why American engineering statics is not simply pounds.
How many slugs are in a stone?
One stone is 0.4351333 slugs. Going the other way, one slug is 2.2981463 stone. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
