How many pounds are in a stone?

There are exactly 14 pounds in one stone. This is a fixed imperial definition used in the United Kingdom and Ireland.

How do I convert pounds to stones manually?

Divide your pound value by 14. The quotient (rounded down) is the number of whole stones. Multiply those whole stones by 14 and subtract from the original pounds to get the remaining pounds. For example, 150 lb ÷ 14 = 10 st 10 lb.

Is the stone unit used in the United States?

No. The stone is not an official unit in the US. It is mainly used in the UK and Ireland for expressing body weight. Americans typically use pounds only.

What is a decimal stone value?

A decimal stone value expresses the entire weight as a fractional number of stones without separating into whole stones and pounds. For example, 150 lb = 10.714 st. This can be useful for calculations or spreadsheets.

Can I convert a fractional pound value like 154.5 lb?

Yes. The converter handles decimal pound inputs. The stone and pounds remainder will both be shown to two decimal places when the input is fractional.
