Convert Slugs to Stone
1 slug is 2.3 st. One slug is exactly 2.29814632546 stone.
One slug is 2.2981463 stone. To convert slugs to stone, multiply by 2.2981463; to go the other way, divide by 2.2981463 or multiply by 0.4351333. The relation is exact but the figure is not: it is a rounding of a number that does not terminate, and it follows from NIST Handbook 44. The mass that one pound-force accelerates at one foot per second squared — 32.174 pounds.

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.
What is a stone?
Fourteen pounds. Still the everyday unit of body weight in Britain and Ireland, and nowhere else.
How many stone are in a slug?
One slug is 2.2981463 stone. Going the other way, one stone is 0.4351333 slugs. 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.
Every weight unit here
The whole group — 15 units with their symbols and the size of each one in kilograms — is on the conversion index, along with every pair it makes. The table above already gives each of them relative to a slug.
