Convert Stone to Centigrams

1 stone is 635,029.32 cg. One stone is exactly 635029.318 centigrams.

One stone is 635029.32 centigrams. To convert stone to centigrams, multiply by 635029.32; to go the other way, divide by 635029.32 or multiply by 1.5747 × 10^-6. 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. Fourteen pounds.

What is a stone?

Fourteen pounds. Still the everyday unit of body weight in Britain and Ireland, and nowhere else.

What is a centigram?

A hundredth of a gram, or ten milligrams. It survives mainly in pharmacology and in school exercises about metric prefixes.

How many centigrams are in a stone?

One stone is 635029.32 centigrams. Going the other way, one centigram is 1.5747 × 10^-6 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.

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 stone.
