How many Kg in a Stone?

We consider that a stone equals 14 pounds known as international avoirdupois pound, defined as 0.45359237 kg.

Thus, the formula is:

[kg] = [st] × 6.35029318

Insert 1 in the [st] field of our formula above, and it follows that the answer to the question how much is a stone in kg is 6.35029318 kilograms.

Similarly, replace the stone placeholder with 3.5 if you want to change 3 1/2 stones to kilograms.

The result of this example mass conversion will be approximately 22.233 kg.
